standard normal set

[OWINO]

may you help me generate a set of 20 observations from standard normal distribution using do, do while and do until loops in SAS

[Shivam]

Hi here are 3 basic programs to illustrate do, do while and do until loop.

hope this helps you to understand.

/*DO LOOP*/
data doloop;
age=5;
do year=2010 to 2030 by 1;
age=age+1;
output;
end;
run;


/*DO WHILE LOOP*/
data doloop;
age=5;
year=2010;
do 
while(year<=2030);
year=year+1;
age=age+1 ;
output;
end;
run;


/*DO UNTIL LOOP*/
data doloop;
age=5;
year=2010;
do
until(year=2030);
year=year+1;
age=age+1 ;
output;
end;
run;

Thanks

Hi and welcome to the SAS Communities 🙂

First of all, please do not double post. You will get the help you need from a single post. 

Regarding your question: When you say "observations", do you mean from a Standard Normal PDF or a random variate or something else? If it is the first, you can do like this (This is 21 obs though)

data Normal;
   do x=-2 to 2 by .2;
      y=pdf('Normal', x, 0, 1);
      output;
   end;
run;

Depending on what is meant, there is also the RAND function which produces random numbers from a normal distribution.
