Hi every body,
Yes, a missing value is a missing value and has no sense to convert it
into 0. Option 2.

A question has come up.
Please consider how you find reading of a CSV file in analysis appropriate:
In a csv file the following data is found:
id, s, pos, sex, ill
1,.,.,f,0
2...... etc (rest of records)
The data in line can be interpreted in two ways:
Option 1:
ID= 1
s= 0.0
pos=0.0
SEX = "f"
ill = 0
Option 2:
ID= 1
s= .
pos=.
SEX = "f"
ill = 0
In other words the question is how to read ",.," should it be:
Option 1: as 0.0 (which is current behaviour)
or Option 2: .
Any comments on desired behaviour appreciated.
regards
