The UNIVARIATE Procedure

Example 9: Displaying a Reference Line on a Normal Probability Plot

Procedure features:

PROC UNIVARIATE statement options:

NOPRINT

INSET statement options:

	FORMAT=
	HEADER=
	POSITION=
	REFPOINT=
	statistical-keyword

PROBPLOT statement options:

	MU=
	NORMAL
	PCTLMINOR
	SIGMA=

VAR statement

Other features:

GOPTIONS statement

SYMBOL statement

Data Set:

DISTRDATA

This example

suppresses the tables of descriptive statistics
creates a normal probability plot
requests a diagonal reference line that corresponds to the normal distribution with estimated parameters and
displays minor tick marks between major tick marks on the percentile axis
enhances the plot by insetting a table of summary statistics
requests graphical enhancements that change symbol type and text font.

Program

goptions htitle=4 htext=3 ftext=swissb ftitle=swissb;

symbol value=star;

proc univariate data=distrdata noprint; var Normal_x;

probplot normal_x /normal(mu=est sigma=est) pctlminor;

inset mean std / format=3.0 header='Normal Parameters' position=(95,5) refpoint=br;

title1 '100 Obs Sampled from a Normal Distribution'; title2 'Normal Probability Plot'; run;

Output

Normal Probability Plot with a Normal Reference Line and a Customized Inset
