stat.statMap: Returns a statistical niftiImage object from a statMap object

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

Returns a statistical niftiImage object from a statMap object

Description

Returns a statistical niftiImage object from a statMap object

Usage

stat.statMap(x, method = c("p", "S", "chisq"))

Arguments

x	the statMap object to extract a coefficient niftiImage from
method	the scale of visualization, chi-squared statistic, effect size (S=RESI), p-value. If df is equal to 1, the maps are scaled by the sign of the coefficient.

Value

a niftiImage object of the chi-square statistical image.

Examples

# loading example data
library(pain21)
pain = pain21()
pdata = pain$data

# fitting regression of images onto study sample size, weights proportional to study sample size
pbjModel2 = lmPBJ(images=pdata$images, form=~n, formred=~1, W = pdata$n, mask=pain$mask, data=pdata)
stat.statMap(pbjModel2)
stat.statMap(pbjModel2, method='chisq')
stat.statMap(pbjModel2, method='S')
