sp_bgsmtr_path: A Bayesian Spatial Model for Imaging Genetics

Description

A plotting function can be used to demonstrate the regularization paths for estimating parameters of each ROI when the spatial model is fitted with multiple values of tuning parameter lambda-squared.

Usage

sp_bgsmtr_path(lambda_v, W_est_list)

Arguments

lambda_v

A vector containing all the different tuning parameter lambda-squared values for model fitting.

W_est_list

A list containing all the estimated coefficients matrices W for each corresponding lambda squared value used in lambda_v for model fitting. Each element of this list is a d-by-c matrix.

Value

Regularization plots files in PDF format for each ROI.
