beta_pal: Beta parameters from interpretable conditions

In softloud/parameterpal: Intepretable parameters for the beta distribution

Description

Rather than knowing intrinsically what parameters are required for a distribution, scientists tend to have a sense of what value they expect a measure to take, how much they expect observations to fall within a certain distance of that value.

Usage

beta_pal(expected_value, within, this_much)

Arguments

expected_value	Expected value of beta distrbution from [0,1].
within	Specify distance this_much falls within.
this_much	What proportion falls within the specified interval.

Details

This solution coded by by this most helpful gist.

Visualise the distribution with beta_plot. See vignette("beta_pal") for derivations and more information.

Value

List of parameters appropriate for rbeta family of functions.
