PermTest: Permutation Test

In GlobalDeviance: Global Deviance Permutation Tests

Description

The function performs a permuatation test with Deviance as test statistic.

Usage

PermTest(xx, formula.full, D.full, D.red, model.dat, glm.family, perm, 
	test.vars, cf, adjust, snowfall.args, snowfall.seed, 
	save.stat.data, file.save, use.save.stat.data, file.use)

Arguments

xx	Dataset (variables x patients).
formula.full	Formula from the full model.
D.full	Designmatrix of the full model.
D.red	Designmatrix of the reduced model.
model.dat	Dataset with covariables.
glm.family	Family for the regression.
perm	Number of permutations.
test.vars	Variables or groups of variables to test.
cf	Combining function for the partial tests.
adjust	Method for p-value adjustment.
snowfall.args	A list with parameters for the initialisation of parallelizing with package snowfall.
snowfall.seed	Start seed.
save.stat.data	Logical value, default is FALSE. Save the permutation and original test statistic.
file.save	File name for saving.
use.save.stat.data	Logical value, default is FALSE. Use the saved permutation and original test statistic.
file.use	File name for data loading.

Value

A list with

statistic	Original test data combined with cf.
df	Degree of freedom for each variable or group of test.vars.
p.value	Permutation p-value for each variable or group of test.vars.
data.perm	Permutation test data.
data.original	Original test data.
