Association Tests

Use this feature to specify one or more association tests to be performed.

The Trend test is selected by default.

Available tests are described in the following table:

Test	Description
Allele	Performs Pearson chi-square tests based on alleles .
Genotype	Performs Pearson chi -square tests based on genotypes .
Trend	Performs the Cochran-Armitage trend test using additive coding (0,1,2) for genotypes homozygous for the major allele , heterozygous , and homozygous for the minor allele , respectively.
Dominant	Performs the Cochran-Armitage trend test using dominant coding (0,1,1) for genotypes homozygous for the major allele, heterozygous, and homozygous for the minor allele, respectively.
Recessive	Performs the Cochran-Armitage trend test using recessive coding (0,0,1) for genotypes homozygous for the major allele, heterozygous, and homozygous for the minor allele, respectively.
MAX	Takes the maximum absolute value of the Z -statistic for the trend, dominant, and recessive tests and simulates random normal variables the number of times specified in the Number of Simulations for MAX Test parameter (if available) to estimate the p-value for this statistic.
RaoScott_ChiSq	Computes the Rao-Scott chi-square statistic for non-continuous traits using PROC SURVEYFREQ. Note : For the Rao-Scott tests, fixed effects and interactions effects are ignored. Refer to the SAS PROC SURVEYFREQ documentation for more information.
RaoScott_F	Compute the Rao-Scott F statistic for non-continuous traits using PROC SURVEYFREQ. Note : For the Rao-Scott tests, fixed effects and interactions effects are ignored. Refer to the SAS PROC SURVEYFREQ documentation for more information.

Note : You might not see all of the association tests described here, depending on the analytical process that you are using.
