This is an Economics Question

When using the SAS software for Economic calculations, write the code for 90th percentile for a data named Battle

Answer 1

In SAS one can calculate the percentiles using a procedure called PROC UNIVARIATE.

Important options which are used while calculating the percentiles in PROC UNIVARIATE are:

1. PCTLPTS: This specifies the percentile levels you want to extract

2. PCTLPRE: This is nothing but one or more prefixes to create the variable name for the variables that will contain the PCTLPTS or percentiles.

3. PCTLNAME: It lists out one or more suffixes to create the variable names that contain PCTLPTS or percentiles.

Given a full data set, you need to run the code for percentile calculation for multiple variables:

Let's assume you need to get 90th percentile for each of the variables namely a,b and c from Battle dataset

The code for 90th percentile would be:

proc univariate data = battle

no print;

var a b c;

output out = outdata PCTLPTS = 90

PCTLNAME= _P90;

run;
