LogisticLogNormal
LogisticLogNormal
is the class for the usual logistic regression model
with a bivariate normal prior on the intercept and log slope.
LogisticLogNormal(mean, cov, ref_dose = 1)

The covariate is the natural logarithm of the dose x
divided by
the reference dose x*
, i.e.:
logit[p(x)] = alpha0 + alpha1 * log(x/x*),
where p(x)
is the probability of observing a DLT for a given dose x
.
The prior
(alpha0, log(alpha1)) ~ Normal(mean, cov).
Typically, end users will not use the .DefaultLogisticLogNormal()
function.
