Extracts the Standard Errors of the Coefficients for the 'Adapted Paik et Al.' Model

Extracts the standard errors for \(\boldsymbol{\beta}\) obtained with the time-dependent frailty model proposed in the 'Adapted Paik et al.' framework.

Usage

coefseAdPaik(object)

Arguments

object

An S3 object of class AdPaik, returned by the main model function (AdPaikModel). This object contains all the optimal parameter estimates.

Value

A named list containing the categories of the standard errors for the optimal parameters.

Details

The se.coef function extracts the standard errors for the estimated parameters from the StandardErrorParameters field in object.

The function validates the structure of object and ensures compatibility with the expected model output. It throws an error if the object is malformed or inconsistent.

Examples

# Example using the 'Academic Dropout' dataset
data(data_dropout)

# Define the formula and time axis for the model
formula <- time_to_event ~ Gender + CFUP + cluster(group)
time_axis <- c(1.0, 1.4, 1.8, 2.3, 3.1, 3.8, 4.3, 5.0, 5.5, 5.8, 6.0)
eps <- 1e-10
categories_range_min <- c(-8, -2, eps, eps, eps)
categories_range_max <- c(-eps, 0, 1 - eps, 1, 10)

# \donttest{
# Run the main model
result <- AdPaikModel(formula, data_dropout, time_axis,
                      categories_range_min, categories_range_max, TRUE)
