postPhi: Metropolis-Hastings step to draw a new value for phi.
In skipTrack: A Bayesian Hierarchical Model that Controls for Non-Adherence in Mobile Menstrual Cycle Tracking
postPhi R Documentation
Metropolis-Hastings step to draw a new value for phi.
Description
In our model the data are drawn from LogN(mu_i + log(c_ij), tau_i). The prior for tau_i
is given as Gamma(thetaiphi, phi). This function uses a MH step to draw a new sample of phi.
Proposal distribution is Gamma(currentPhirhoPhi, rhoPhi).
Note that we parameterize with RATE, not SCALE.
Usage
postPhi(taui, thetai, currentPhi, rhoPhi = 1000)
Arguments
taui
Numeric vector, individuals precisions.
thetai
Numeric vector. individuals precisions means (estimate)
currentPhi
Previous draw of phi
rhoPhi
Proposal rate for gamma distribution that draws proposal for phi, default is 1000.
Value
Numeric, new draw of phi
