bootStats: Computes Statistical Map for Neuroimaging Data

In neuroconductor/pbj: Parametric Bootstrap Joint Testing Procedures for Neuroimaging

Description

This function computes a statistical map and residuals which are the objects necessary to perform the parametric bootstrap joint (PBJ) inference procedure.

Usage

bootStats(images, coefficients = NULL, X, Xred,
  statistic = function(stat, ...) stat, ...)

Arguments

images	An n by V matrix of voxels inside the brain.
coefficients	An n by V matrix of parameter estimates to subtract from the bootstrapped values. If computing p-values this should be the observed parameter estimates. If computing confidence intervals then this should be NULL (the default).
X	Design matrix for the full model.
Xred	Design matrix for the reduced model.
statistic	A function of the form statistic(stat, ...) that returns a statistic of interest.
...	Arguments passed to statistic function.

Value

Returns a vector of the resulting estimate
