estimate_sd_error {cprobit} R Documentation

## Inpernal function: estimate the SD of error terms in the difference model

### Description

Inpernal function: estimate the SD of error terms in the difference model

### Usage

estimate_sd_error(beta_c, y1, y2, lambda = NA, design_mat_diff)


### Arguments

 beta_c Numeric vector of Step 1 estimates. y1 Numeric vector of the observed outcome at observation time 1. y2 Numeric vector of the observed outcome at observation time 2. lambda The Box-Cox transformation parameter. Default is NA, indicating no need for a transformation. See Details. design_mat_diff Numeric matrix of the design matrix for difference.

### Value

Returns the estimate for sigma_delta if lambda = NULL, or sigma_delta_lambda on the transformed scale.
