LARGEST

LARGEST (LET)

Let Subcommand

Extract the largest elements of a variable.

This is a generalization of the MAXIMUM command. However, instead of returning the single largest value, it returns the user specified number of largest values.

The values will be returned in sorted order. If the requested number of largest values is less than 1, then an error will be returned. If the requested number of largest values is greater than the number of observations in the response variable, then the full response variable will be returned in sorted order.

LET <y> = LARGEST <x> <nval>                         <SUBSET/EXCEPT/FOR>
where <x> is a response variable;
            <nval> is a number or parameter that specifies how many values to extract;
            <y> is a variable that contains the largest values;
and where the <SUBSET/EXCEPT/FOR qualification> is optional.

LET NVAL = 3
LET Y = LARGEST X NVAL


LET Y = LARGEST X 3 LET Y = LARGEST X 5 LET Y = LARGEST X 5 FOR I = 1 1 500
