Fit Contrasts for Linear Model (Default Method)

Description

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.
