Chi-Square Goodness of Fit
--------------------------
Syntax
------
csgof variable [, expperc( expected percentages ) ]
The csgof command performs a chi-square goodness of fit test. This
allows you to test whether the observed percentages for a categorical
variable are significantly different from expected percentages.
The expected percentages are supplied via expperc( ) and are listed
simply as a series of numbers. The order of the values in expperc( )
should correspond to the sorted order of the variable.
Note that the data is expected to have one observation per subject.
You may need to use the expand command to make the data file
have one observation per subject.
Examples
