Verification: After writing a program, if you want to check
is it correct or not. Ex. By using Debuging
Validation: Is the process, recorded evidence of the
actions in a sequence and gives the same outputs with out
any deviation of the given task (i.e accuracy, integrity
etc).

verification :
is the value is correct ot not
validation :
is the value is existable or not
EX:
0 <= p(x) <= 1
validation: value of p(x) must be lies between 0 and 1
other wise it's not validate result
verification: check again the calculation process to obtain
the valid value for p(x).......
p(x) means probability of x(Success)

What are the functions which are used for character handling functions?
Dear all, proc means data=dsn noprint completetypes; class trtmntgroup /preloadfmt; output out=tot n=n; format trtmntgroup trtf. ; by vstgrp descending severity; run; This is the code I used for AE table. I got the values without giving the variable ‘trtmntgroup(numeric)’ in var statement. And if I give the var statement for that variable i’m getting the same values.How is that possible? What is the difference between class and var statement? Could any one explain me how does proc means work at the back end. And what is the difference between _freq_ value and N value in proc means. Thanks and regards, Rajesh.
