Description

Helper functions for analytical solutions.

Function Documentation

◆ check_for_analytical()

int check_for_analytical	(	int	dist_id,
		int	primary_id )

Check if an analytical solution exists for the given distribution combination

Parameters

dist_id	Distribution identifier for the delay distribution
primary_id	Distribution identifier for the primary distribution

Returns: 1 if an analytical solution exists, 0 otherwise

◆ log_weibull_g()

real log_weibull_g	(	real	t,
		real	shape,
		real	scale )

Compute the log of the lower incomplete gamma function

This function is used in the analytical solution for the primary censored Weibull distribution with uniform primary censoring. It corresponds to the g(t; λ, k) function described in the analytic solutions document.
