Thanks for contributing this @prabasaj. Similar functionality to combine epidemiological parameter distributions was added to the package in #388 using mixture distributions to combine individual distributions.
I will leave this issue open as we can explore this method of combining estimates in the next development cycle (v0.4.0).
Suggesting an option to combine multiple estimates of the same parameter set (shape and scale of gamma distribution fitted to incubation period for Ebola, for example, across 5 studies). Here's some basic code to start with:
Weighted combination of multivariate estimates and population covariance User supplied weights may be some combination: (weight) = (effective sample size) X (quality weight) X (relevance weight) Neglects sample size corrections and is based on definition Includes option of weighting by inverse radius of covariance matrix estimate set is a list of estimate-lists: list(est1 = list(mean, covariance, weight), ...)
Example: combining bivariate parameter estimates (shape and scale of gamma distributions mean=c(shape, scale), for example)
