PROC Functions

SAS functions
perform arithmetic operations
compute sample statistics (for example: sum, mean, and standard deviation)
manipulate SAS dates and process character values
perform many other tasks.

Sample statistics functions ignore missing values.

data onboard;
set work.pilotdata; (copy from dataset)
Total=sum(FirstClass,Economy);
run;

avgX = mean(of x1-x10);
stdX = std(of x1-x10);
minX = min(of x1-x10);
maxX = max(of x1-x10);
rangeX = range(of x1-x10);


Other useful sample statistic functions are:

MAX(argument,...) returns the largest value

MIN(argument,...) returns the smallest value

MEAN(argument,...) returns the arithmetic mean (average)

N(argument,....) returns the number of nonmissing arguments

NMISS(argument,...) returns the number of missing values

STD(argument,...) returns the standard deviation

STDERR(argument,...) returns the standard error of the mean

VAR(argument,...) returns the variance
