Initialize a heteroskedastic Gaussian likelihood node

This function constructs a likelihood object to represent a heteroskedastic Gaussian likelihood node.

Usage

Hetero(input_dim = NULL)

input_dim: a vector of length two that contains the indices of two GP nodes in the feeding layer whose outputs feed into this likelihood node. When set to NULL, all outputs from GP nodes in the feeding layer feed into this likelihood node, and in such a case one needs to ensure that only two GP nodes are specified in the feeding layer. Defaults to NULL.

A 'python' object to represent a heteroskedastic Gaussian likelihood node.

The heteroskedastic Gaussian likelihood node can only be linked to two feeding GP nodes.
