sigmanoise_sampling {BICORN}

Fitting Residule Variance Sampling Function

Description

Function 'sigmanoise_sampling' estimates the variance of overal gene expression fitting residuals, according to an inverse-gamma distribution.

Usage

sigma_A

variance of regulatory strength

sigma_baseline

variance of gene expression baseline activity

sigma_X

variance of transcription factor activity

alpha

hyper-parameter for inverse-gamma distribution

beta

hyper-parameter for inverse-gamma distribution
