Hi i am trying to estimate a logic model. However my explanotary flag variables both include 0, "." (missing values) and i need to code missing values as "0"
Because i have about 40 variables do you know an esay way yo solve this problem
I am not sure what you mean by a "logic model" (perhaps logistic?) nor am I sure what you mean by "flag variables".
Furthermore, coding missing as 0 is often a mistake.
Nevertheless, if you want to do so you can do it in an array (the following code is not tested):
data new;
set old;
array misszero (*) YOUR LIST OF VARIABLES HERE;
do i = 1 to dim(misszero);
if misszero(i) = . then misszero(i) = 0;
end;
run;
yes i was trying to build a logistic regression
i am trying to implement your code to my project but unfortunately still i couldnt make it
however thank you very much for your interest
What do you mean 'couldn't make it'? What was the error message?
