SPC commands for testing and other aspects of EpiData Analysis v2.1

by epidata-list＠lists.umanitoba.ca

Dear All We are approaching finalisation of the current SPC graph implementation in EpiData Analysis. But await comments and further testing by users and specialists. Some errors were found in build 155 for Ichart-moving range charts. Today build 156 has been uploaded. Since public release of v2.1.0 the following SPC graphs have been implemented in the test version 2.1.1. build 156 available from http://www.epidata.dk/testing.php : Gchart, UChart, XBar (Sigma and Range), CChart, Ichart moving range Apart from the new commands it would be good if users would comment further on the new aspects of v2.1, e.g. the current implementation of lifetables. How is it working in practice, is the help file sufficient etc. An issue was raised on the list regarding use of "actuarial versus Kaplan-Meier" principles. It seems as if this relates to use of floating point variables (e.g. 1.4 week) for the time variable, which now is read as a rounded integer variable. Following further clarification I will notify here. Next in line in the development is release of a translation tool, such that analysis can be translated in a "smooth" way. And in analysis further implementation of "set ...." will be added to facilitate easier default setting of user options. The following general "set" will be added: set graph option=" ......" (for all graphs) set table option=" ......" (for cross tables and frequency tables) set spc option=" ..... " (for spc graphs and analysis) Possible also the following will be added for means, describe etc.: set descriptive option="..... " regards Jens Lauritsen EpiData Association

Date-illegal entry

by epidata-list＠lists.umanitoba.ca

Thank you for your response to my date question. During entry, if the date field is not applicable to a certain record (whereas I do not need to enter a date for that specific record, rather skip it) what do I designate as my skip code. I did have -77, but when I would enter that, it would say it was an illegal entry. How do I write the code, so that a skip is -77, and it still be a legal entry in some instances? legdat RANGE 01/01/1900 31/12/2008 LEGAL 30/12/2009 24/11/2008 END END (somewhere in there, I need to put it a skip code) Thank you for your time, Lindsay Lindsay Iser, M.A. University of South Florida Florida Mental Health Institute Department of Aging and Mental Health 13301 N.

Algorithm RUT, numeric field

by epidata-list＠lists.umanitoba.ca

I'm from Chile (South America), my native language is Spanis... I write a draft text below. Estimados amigos, Me gustaria saber si puedo leer un campo numérico y descomponer individualmente sus dígitos de aquella cifra. Esto, con la intención de obtener el digito verificador(dv) de un RUT. Intenté un algoritmo, pero tengo que hacer campos individuales para cada digito, que no es la idea, lo que hago es: R1# R2# R3# R4# R5# R6# R7# R8# -dv<A> entonces ingreso: 3 0 6 8 6 9 5 7 -dv 4(este surge del algoritmo) Me gustaria que fuese asi: RUT ######## -dv<A> (este surga del algoritmo) 30686957 -dv 4 Les agradesco mucha vuestra colaboración. Carlos Ortega Areyte Academico Procedimiento para obtener el dígito verificador. -------------------------------------------------- El RUT consta de dos partes, el número y el dígito verificador separados por un guión. En el siguiente ejemplo se toma como RUT el número 30.686.957- X, donde 30.686.957 es el número del RUT y X será el dígito verificador que se desea verificar o conocer: - Se procede a tomar el número de RUT de derecha a izquierda, multiplicando cada dígito por los números que componen la serie numérica 2,3,4,5,6,7; y sumando el resultado de estos productos, como se muestra a continuación (si se ha aplicado la serie hasta el 7 y quedan dígitos por multiplicar, se comienza la serie nuevamente): En el ejemplo: 7 × 2 = 14, 5 × 3 = 15, 9 × 4 = 36, 6 × 5 = 30, 8 × 6 = 48, 6 × 7 = 42, 0 × 2 = 0, 3 × 3 = 9, entonces la suma de los productos es: 14+15+36+30+48+42+0+9 = 194 - Al número obtenido por la suma del producto de cada dígito por la serie ya mencionada, se le aplica módulo 11, o sea, se divide por 11 y se determina el resto de la división. En el ejemplo: 194: 11 = 17 Resto: 7 Ahora a 11 se le resta el resto: En el ejemplo: 11 - 7 = 4 Si el resultado es 11, el dígito verificador será 0. Si el resultado es 10, el dígito verificador será K. En otro caso el resultado será el dígito verificador. Como en el ejemplo el resultado de la resta es 4, el dígito verificador es 4. Por ende, el RUT del ejemplo es el 30.686.957-4. Por cierto, este ejemplo lo Obtuve de es.wikipedia.org ************** ************** ******************************* This is a translation, I'm from Chile (South America), my native language is Spanish ... sorry my little English. Dear friends, I would like to know if I can read a numeric field and break down their individual one-digit figure. This, with the intention of obtaining the digit verifier (dv) of a RUT. I tried an algorithm, but I have to make individual fields for each digit, that is not the idea, what I do is: R1 # R2 # R3 # R4 # R5 # R6 # # R7 R8 # -dv <A> then login: 3 0 6 8 6 9 5 7 dv- 4 (this born from the algorithm) I would like it to be like this: RUT ######## -dv <A> (this born from the algorithm) 30686957 -dv 4 Thank you very much for your cooperation. Carlos Ortega Areyte Academic Obtain the procedure for verifying digit. -------------------------------------------------- The RUT is in two parts, the number and verifying digit separated by a hyphen. In the following example is taken as RUT number 30686957 - X, where 30686957 is the number of RUT and X will be the verifying digit you want to know or verify: - We shall proceed to take the number of RUT from right to left, by multiplying each digit numbers that make up the numerical series 2,3,4,5,6,7; and adding the output of these products, as shown below (if the series has been implemented and are up to 7 digits per leverage, the series begins again): In the example: 7 x 2 = 14 5 x 3 = 15, 9 × 4 = 36 6 x 5 = 30, 8 × 6 = 48 6 x 7 = 42 0 x 2 = 0, 3 x 3 = 9 then the sum of products is: 14 +15 +36 +30 +48 +42 +0 +9 = 194 - The number obtained by the amount of the proceeds of each digit in the series already mentioned, it is covered module 11, in other words, is divided by 11 and determining the rest of the division. In the example: 194: 11 = 17 Rest: 7 Now he is a 11 subtracts the rest: In the example: 11-7 = 4 If the result is 11, the verifier digit will be 0. If the result is 10, will be verifying digit K. Otherwise the result will be verifying digit. As in the example the result of the remainder is 4, the digit verifier is 4. Thus, the RUT's example is the 30.686.957- 4. this example of what I got es.wikipedia.org -- Carlos A. Ortega Areyte Prof. de Matemática y Computación Magíster en Bioestadística ACADÉMICO

I have tried several times to fix this, but for some reason EpiData is telling me it is illegal. 1. fa163axxxx RANGE 01/01/1900 12/31/2008 LEGAL 99 -77 88 END MUSTENTER END 1: i. No date will satisfy the commands. ii. When you do put a date it, it reads : "Illegal entry- Legal values are 01/01/1900-12/31/2008, -77, 99, 88" iii.

sort field

by epidata-list＠lists.umanitoba.ca

I have 300 records, each was stored in a disorderly file, "failure.REC" So, when I preview the records, in step 5.Document (view data) this showing: id age sex event 2 0 1 25 80 1 1 28 125 0 1 36 3 1 1 19 18 0 1 44 23 0 0 12 . . . 10 0 0 21 300 0 1 39 287 1 0 58 1 0 1 23 How can I get these same records appear sorted by id, in the file failure.REC when I try to enter an new records? So when you enter the id 300, so this can then enter the id 300? I managed this trick, STATA by exporting to ... order by id, the new failure.dta Then, import failure.dta to a new failure.REC ... I am working. But it's also complicated and I do not retain the original format, let alone id ###### sex ###### event ###### age ###### erasing {id} What is the id of the questionnaire? # # # {sex} Indicate sex # {event} What is the patient's condition at the end of the period? # {age} Age at onset of the study # # I hope you understand my question.

Charting SPC (statistical process control) data with EpiData Analysis

by epidata-list＠lists.umanitoba.ca

Shakeel asked on the list: "Is there any way I can create SPC Charts that show actual counts (e.g of MRSA) against targets?" There are three SPC strategies here, depending on the frequency of MRSA infections: 1. If rare: Record date of incidence (e.g. dateinci) and save in a rec file, then in analysis (latest test release): read mrsadata ; Gchart dateinci /t 2. If a certain proportion of patients. Record dates (e.g. hospdate) number of infections (count) and total volume of patients (total): read mrsadata ; pchart hospdate count total /t 3. If you only have the counts, but not the totals, you can either do a runchart or ichart: read mrsadata ; runchart hospdate count /t ; Ichart hospdate count /t; In other words it depends on the nature of the contact to the patients, the similarity of the underlying data in subgroups etc. For adding the target an option with the graphs is required, e.g.: Say the target was 1 % of all patients with a certain infection: pchart hospdate count total /t /yline=0.1 /sub="Target indicated at Y=10%" A good advice is always regardless of the above, that a lot can often be learned by just plotting the raw data on a time scale. A "manual" for SPC is underway, but meanwhile read some of the textbooks available. regards Jens Lauritsen EpiData Association

Selecting Dates

by epidata-list＠lists.umanitoba.ca

Hello Could you please advise what I am doing wrong with my date selection process. I have a field called visitdate. Format = dd/mm/yyyy. The field itself is OK because FREQ visitdate works fine. My problem is when I try to select dates less than 1 July ( 01/07/2008) When I try select visitdate < "01/07/2008" I get an error message "Type Date is incompatible with type String operation aborted" When I try select visitdate < 01/07/2008 I get an error message "Type Date is incompatible with type Float Operation aborted" The only way I could find in the end was to use the month function to create a new field called visitmonth from visitdate and then select visit month <7. This worked, but I want to be able to select on the original visitdate field. Could someone help please? thanks Christine Christine Roseveare Analyst Regional Public Health 570 9194 027 495 9671 >>> <epidata-list-request(a)lists.umanitoba.ca> 29/11/2007 7:02 a.m. >>> Send EpiData-list mailing list submissions to epidata-list(a)lists.umanitoba.ca To subscribe or unsubscribe via the World Wide Web, visit http://lists.umanitoba.ca/mailman/listinfo/epidata-list or, via email, send a message with subject or body 'help' to epidata-list-request(a)lists.umanitoba.ca You can reach the person managing the list at epidata-list-owner(a)lists.umanitoba.ca When replying, please edit your Subject line so it is more specific than "Re: Contents of EpiData-list digest..." -- The information contained in this email and any attachments is confidential and may be legally privileged.
