check.categories_params: Check Correctness of Parameters Categories

In TimeDepFrail: Time Dependent Shared Frailty Cox Model

Check Correctness of Parameters Categories

Description

The function controls that the provided parameters categories have a length equal to the number of categories required by the model parameters. For the current model, the number of categories is 5 because there are five blocks of unkown parameters (\phi_k \forall k, \beta_r \forall r, \mu_1, \nu, \gamma_k \forall k).

Moreover, it also controls that the minimum value of a parameter category is actually less than or eqaul to the maximum value for the same category.

Usage

check.categories_params(
  n_categories,
  categories_range_min,
  categories_range_max
)

Arguments

n_categories	Number of categories expected by the model. For the current model, they are 5.
categories_range_min	Numerical vector of length 5, containing the minimum ranges for the parameters beloning to those categories.
categories_range_max	Numerical vector of length equal to 5, containing the maximum ranges for the parameters belonging to those categories.

Value

An error if the any condition is not satisfied.
