F.mp: F-tests for massively parallel linear models

In vows: Voxelwise Semiparametrics

Description

Performs F-tests for removing one or more terms from each of a large number of models with common design matrix.

Usage

F.mp(formula, which)

Arguments

formula	a formula such as "Y ~ X", where Y is an n \times V response matrix and X is an n \times p design matrix common to all V models.
which	number or vector indicating which column(s) of the model matrix are to be tested for removal from the model.

Value

F	F-statistics for each of the models.
df1	numerator degrees of freedom.
df2	denominator degrees of freedom.
pvalue	upper-tailed p-value.
X	design matrix.
