Purpose: Syntax
N(n1,n2,n3,….,n);
N count no. of non-missing value
Nmiss(n1,n2,n3,….,n);
NMISS count no. of missing value
largest(k,n1,n2,n3,….,n);
LARGEST Returns nth largest value
smallest(k,n1,n2,n3,….,n);
SMALLEST Returns nth smallest value

**k is used in largest and smallest function which indicates the k value that we want.
th

Program 4.2: Output:

As you observe the result window you can notice by using N function we can count the number of non-

missing value and by use NMISS we can count the number of missing value. Then come to LARGEST
function when we use K=1, then we got the 1 largest value .if we use k=2 then we get the 2 largest
nd
st
value. SMALLEST function also works on same concept as LARGEST.
