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.
hb_s_tau(precision_ratio = 0.5, sigma = 1, n = 100)Positive numeric vector of elements between 0 and 1 with target precision ratios.
Positive numeric vector of residual standard deviations.
Number of non-missing patients.
Numeric of length equal to length(precision_ratio) and
length(sigma), suggested values of s_tau for each element of
precision_ratio and sigma.
See the hierarchical model section of the methods vignette for details.
