Is your feature request related to a problem? Please describe.
As part of gearing up for the upcoming flu season, I’ve been refining our priors for influenza config files. I’ve stitched together posterior parameter sets from our cross-seasonal resampling and rejection sampling to empirically inform prior choices.
Based on AIC comparisons (ΔAIC ≥ 4 marked with ★), Gamma and Weibull distributions frequently fit these empirical posteriors better than LogNormal, as shown in the attached plots:
I'd like to request support for Gamma and Weibull priors in FlepiMoP—this should be relatively straightforward, likely just a wrapper around scipy.stats.gamma and weibull_min, analogous to how lognorm is currently handled.
Is your feature request related to a new application, scenario round, pathogen? Please describe.
This would be generally useful, but is motivated by the upcoming influenza round.
