calculate_beta: Calculate the beta hyperparameter for popReconstruct variance...

In ihmeuw-demographics/popMethods: Methods for Population Estimation

Description

Helper function for calculating the beta parameter of an inverse gamma distribution given absolute deviation from the popReconstruct elicitation statement. Used for quantifying measurement error in popReconstruct components.

Usage

calculate_beta(abs_deviation, p, alpha, log_transform)

Arguments

abs_deviation	[numeric(1)] Expert opinion about the absolute deviation η_{ν} of the initial point estimates for a given probability interval p_{ν}.
p	[numeric(1)] Central p_{ν}% probability interval used in elicitation statement.
alpha	[numeric(1)] Alpha (shape) parameter of inverse gamma distribution.
log_transform	[logical(1)] Whether model component is log transformed in the popReconstruct model.

Value

[numeric(1)] Beta (scale) parameter of inverse gamma distribution for the variance of the popReconstruct model component.
