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 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.
