Tools to Support the Sheffield Elicitation Framework
Description
Implements various methods for eliciting a probability
distribution for a single parameter from an expert or a group of
experts. The expert provides a small number of probability judgements,
corresponding to points on his or her cumulative distribution
function. A range of parametric distributions can then be fitted and
displayed, with feedback provided in the form of fitted probabilities
and percentiles. For multiple experts, a weighted linear pool can be
calculated. Also includes functions for eliciting beliefs about
population distributions; eliciting multivariate distributions using a
Gaussian copula; eliciting a Dirichlet distribution; eliciting
distributions for variance parameters in a random effects
meta-analysis model; survival extrapolation. R Shiny apps for most of the methods are
included.
