TrfJacobian: Computes determinant of Jacobian of Marginal Transform (MT) method.

Description

Computes determinant of Jacobian of Marginal Transform (MT) method.

Usage

TrfJacobian(z, alpha, beta, kappa, offset_scale, offset_shape)

Arguments

z

GPD(offset_shape, offset_scale)-distributed data.

alpha

Shape parameter of output data.

beta

Part of scale parameter of output data (beta + kappa). Should be positive.

kappa

Part of scale parameter of output data. Should be positive.

offset_scale

Scale parameter of input data. Should be positive.

offset_shape

Shape parameter of input data.

Value

Transformed scale parameter given original data parameters.
