Superseded:
suggest a value of the s_tau
hyperparameter
to roughly target a specified minimum amount of borrowing
in the hierarchical model with the uniform prior.
Only use if a diffuse prior on tau
is not feasible.
hbl_s_tau(precision_ratio = 0.5, sigma = 1, n = 100)
Numeric of length equal to length(precision_ratio)
and
length(sigma)
, suggested values of s_tau for each element of
precision_ratio
and sigma
.
The target minimum amount of borrowing
is expressed in the precision_ratio
argument.
The precision ratio is a metric that quantifies the amount of
borrowing in the hierarchical model. See the "Methods" vignette
for details.
