Test whether a shape parameter of is in the bounds required for a valid phase-type approximation

Usage

gamma_shape_in_bounds(shape, nphase)

weibull_shape_in_bounds(shape, nphase)

Arguments

shape

Shape parameter or vector)

nphase

Number of phases

Value

Vector or logicals, whether each shape parameter is in the bounds require for a phase-type approximation with that number of phases.

Details

Also verifies that the parameter satisfies Case 1 of Theorem 1 in Bobbio et al.
