margModelPosterior: Marginal Model Posterior

Description

Compute the marginal model posterior.

Usage

margModelPosterior(runInfoObj,allocation)

Value

It returns a file in the output folder, with name ending in "_margModPost.txt", that contains the marginal model posterior. It also returns a list. The first argument is called margModPost and it is the mean of the values of the marginal model posterior as they appear in the file ending in "_margModPost.txt" in the output folder. The second argument is an updated runInfoObj which also include some hyperparameter values.

Arguments

runInfoObj

An object of type runInfoObj.

allocation

By default, if allocation is not provided, the _z.txt file is read to compute the marginal model posterior for all the partitions available there. If allocation is equal to a vector that corresponds to a partition, the marginal model posterior is computed for that given partition.
