hb_s_tau: Superseded suggest s_tau given a uniform prior on tau.

In historicalborrow: Non-Longitudinal Bayesian Historical Borrowing Models

Superseded suggest s_tau given a uniform prior on tau.

Description

For the uniform prior on tau, suggest a value of the s_tau hyperparameter to achieve a given amount of borrowing in the hierarchical model. Only use if a diffuse prior on tau is not feasible.

Usage

hb_s_tau(precision_ratio = 0.5, sigma = 1, n = 100)

Arguments

precision_ratio	Positive numeric vector of elements between 0 and 1 with target precision ratios.
sigma	Positive numeric vector of residual standard deviations.
n	Number of non-missing patients.

Details

See the hierarchical model section of the methods vignette for details.

Value

Numeric of length equal to length(precision_ratio) and length(sigma), suggested values of s_tau for each element of precision_ratio and sigma.

Examples

hb_s_tau(precision_ratio = 0.5, sigma = 1, n = 100)
