Example 7: Crosstabulation with Measures of Association and Chi-Square Tests
Details
To compute measures
of association of the row and column variable, you can add the MEASURE
option to the CROSSTAB statement. ASSOCIATION is an alias for the
MEASURE option. You can also request Chi-Square statistics for the
test of independence between row and column variable with the CHISQ
option.
The following statements
request a crosstabulation of the Cylinders and Origin variables for
the CARS data set. The statements also request measures of association
and Chi-Square statistics. The NOMISS option is used to exclude levels
of the variables that correspond to missing values.

-
The variables to use for the columns and rows are specified in the CROSSTAB statement.
-
The NOMISS option excludes levels that have missing values. Note that by default the FREQ procedure excludes levels with missing values, whereas the IMSTAT procedure includes those as valid levels.
