X

How can i make a new column with the mean days for each city even though i have missing values ?
I want this out out
City meanX 2.5Y 3.5
City mean
X 2.5
Y 3.5

PROC MEANS or PROC SUMMARY will do the calculations and properly ignore the missings, and allow you to create the new data set.
proc summary data=have nway; class city; var days; output out=want mean=; run;
The mean function ignores missing values, so you can use it in a proc sql to obtain what you want.
proc sql; create table want as select city , mean(days) as mean from have group by city; quit;
