zoid-package | The 'zoid' package.
broken_stick | Random generation of datasets using the dirichlet broken stick method
chinook | Data from Satterthwaite, W.H., Ciancio, J., Crandall, E., Palmer-Zwahlen, M.L., Grover, A.M., O’Farrell, M.R., Anson, E.C., Mohr, M.S. & Garza, J.C. (2015). Stock composition and ocean spatial distribution from California recreational chinook salmon fisheries using genetic stock identification. Fisheries Research, 170, 166–178. The data genetic data collected from port-based sampling of recreationally-landed Chinook salmon in California from 1998-2002.
coddiet | Data from Magnussen, E. 2011. Food and feeding habits of cod (Gadus morhua) on the Faroe Bank. – ICES Journal of Marine Science, 68: 1909–1917. The data here are Table 3 from the paper, with sample proportions (columns w) multiplied by total weight to yield total grams (g) for each sample-diet item combination. Dashes have been replaced with 0s.
fit_dirichlet | Extract point estimates of compositions from fitted model.
fit_prior | Find appropriate standard deviations for prior
fit_zoid | Fit a trinomial mixture model with Stan
get_fitted | Extract estimates of predicted latent proportions.
get_pars | Extract parameters from fitted model.
parse_re_formula | Fit a trinomial mixture model that optionally includes covariates to estimate effects of factor or continuous variables on proportions.
rmspe_calc | Find appropriate prior for a given target distribution.
trinomix | The 'zoid' package.
