Including missing ' .' into summary statistics

[deleted_user]

In proc mean or proc summary, statistics remove the observation to perform mean caculation if it is '.'

Is there any option in Proc Mean or Summary that can perform mean caculation which include observation with '.' as observation ?

I don't want to change '.' to 0 in data step.

if you want to treat missing as zero, you'll need to do that before the proc.
However, you can use a VIEW which means you have only one copy of your data. You can create either an SQL view or a Data Step view, like: [pre]data Mzero /view= mZero ;
set your.original_data ;
array nums _numeric_ ;
do over nums ;
nums = coalesce( nums, 0 );
end ;
run ;
proc means data= Mzero ;
run;[/pre]

good luck

Thanks!

It just confirm that there is no option in Proc Mean or summary to caculate statistics to include '.' as a valid observation. I have to replce '.' as 0 in data step first.
