In cvraut/iBAGpkg: integrative Bayesian Analysis of the Genome

construct.priors

Description

constructs the priors for the clinical model. includes basic bound checks

Usage

construct.priors()

Arguments

r_tau	(0.001) hyperparameter for residual precision tau
d_tau	(0.001) hyperparameter for residual precision tau
d_pi	(1) hyperparameter for prob of kth coefficient != 0
r_pi	(1) hyperparameter for prob of kth coefficient != 0
r_gamma	(0.001) hyperparameter for precision of kth coefficient
d_gamma	(0.001) hyperparameter for precision of kth coefficient

Details

follows from https://arxiv.org/pdf/1811.02962v1.pdf section 2.3

• (residual precision) tau ~ Gamma(r_tau,d_tau)

• (prob of kth coefficient != 0) pi_k ~ Beta(d_pi, r_pi)

• (precision of kth coefficient) gamma_k ~ Gamma(r_gamma,d_gamma) Note: all parameters must be positive (>0)

Value

list with the following hyperparamenters accessible by index or param name
