Fit Contrasts for Linear Model (Default Method) — fit_contrasts.default • fmrireg

This function calculates contrasts for a fitted linear model.

Usage

# Default S3 method
fit_contrasts(object, conmat, colind, se = TRUE, ...)

Arguments

object: The fitted linear model object.
conmat: The contrast matrix or contrast vector.
colind: The subset column indices in the design associated with the contrast.
se: Whether to compute standard errors, t-statistics, and p-values (default: TRUE).
...: Additional arguments (unused)

Value

A list containing the following elements:

conmat: Contrast matrix.
sigma: Residual standard error.
df.residual: Degrees of freedom for residuals.
estimate: Estimated contrasts.
se: Standard errors of the contrasts (if se = TRUE).
stat: t-statistics for the contrasts (if se = TRUE).
prob: Probabilities associated with the t-statistics (if se = TRUE).
stat_type: Type of the statistics calculated.
