We are gradually adding all functionality of Analysis classic.

The options cannot have a blank from ! to the actual option××: Freq v1 v19 !ci; Not Freq v1 v19 ! Ci

For select in analysis two approaches :

Read datafile !c ; Select v19 <> 1 do drop data; // now we do not need select ;

Tab v2 v4 !pr !d1!t;

// the same analysis for the other part; Read datafile !c ; Select v19 = 1 do drop data; // now we do not need select ;

Tab v2 v4 !pr !d1!t;

Approach 2 Read datafile !c ; Select v19 = 1 do Begin Tab v2 v4 !pr !d1!t; Tab v2 v6 !pr !d1!t; .... Any other command within this select

End; Select v19 <> 1 do Begin Tab v2 v4 !pr !d1!t; Tab v2 v6 !pr !d1!t; .... Any other command within this select

End;

Hello,

For training, I'm trying to understand the new version of "Analysis".

A few comments :

• The command "freq var ! r;" (as shown in the guide) doesn't work, but

"freq var ! pr" is OK.

Strictly speaking and on the educational plan, the percentages presented with "freq" are in columns : "freq var ! c;" or "freq var ! pc;" would be more logical.

• To select a part of the file, I noted, (as an example for a

frequency) the command "select (var1 <3) do freq var2 ! pr;".

Should we repeat with each command "select (var1 <3) do"?

Is there a way, like the old "select", to select part of the file for further commands?

• The command (example) "select (var1 = 3) do var1: = 2;" is quite

complicated compared to that "if ... then ...."

• How to create a new numeric variable with 3 digits and 2 decimal

places? As in the old "define var ###. ##"?

• When will the "regress" commands and the graph commands (including

scatter with a regression line as in the old "Epi-Info" ...?

Thank you for your help.
