Create an AR(1) GLM model for fMRI data

This function creates a model specification for MRI data with an AR(1) error structure. The model includes beta parameters for the design matrix, a rho parameter for the autocorrelation, and a standard deviation parameter for the noise.

Usage

MRI_AR1()

Value

A list containing the model specifications

Details

The AR(1) model accounts for temporal autocorrelation in the data, where each timepoint is correlated with the previous timepoint according to the rho parameter.

Examples

# Create an AR(1) GLM model for fMRI data
model_spec <- MRI_AR1()
