postTaui

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(thetai*phi, phi). This function draws from the conditional
posterior of tau_i. Note that we parameterize with RATE, not SCALE.

Implements a Bayesian hierarchical model designed to identify skips in mobile menstrual cycle self-tracking on mobile apps. Future developments will allow for the inclusion of covariates affecting cycle mean and regularity, as well as extra information regarding tracking non-adherence. Main methods to be outlined in a forthcoming paper, with alternative models from Li et al. (2022) <doi:10.1093/jamia/ocab182>.
