Calculates statistics and coefficients for linear model of specified anat structure

Description

Calculates statistics and coefficients for linear model of specified anat structure

Usage

anatLm(formula, data, anat, subset = NULL, weights = NULL)

Arguments

formula	a model formula. The RHS of the formula may contain one term with a matrix. If so only the + operator may be used, and only two terms may appear on the RHS
data	a data.frame containing variables in formula
anat	an array of atlas labels vs subject data
subset	rows to be used, by default all are used
weights	An optional set of weights to use the regression, must be one per subject

Value

Returns an object containing the R-Squared,value,coefficients,F and t statistcs that can be passed directly into anatFDR. Additionally has the attributes for model,stat type and degrees of freedom.
