check.range_params: Check Correctness of Input Parameters

In TimeDepFrail: Time Dependent Shared Frailty Cox Model

Check Correctness of Input Parameters

Description

The function controls that the input parameter vector have a length equal to the theoretical one required by the model and that each parameter properly belongs to its range.

Usage

check.range_params(optimal_params, params_range_min, params_range_max)

Arguments

optimal_params	Numerical vector of length equal to the number of model parameters. For the 'Adapted Paik et al.'s Model' it can be computed as: n_p = 2L + R + 2, where L stands for the number of intervals of the time domain and R the number of regressors of the dataset.
params_range_min	Numerical vector of length equal to the number of model parameters (n_p) and containing the minimum range for each parameter.
params_range_max	Numerical vector of length equal to the number of model parameters (n_p) and containing the maximum range for each parameter.

Value

An error if any condition is not satisfied.
