lognormal() defines a one-response positive continuous distribution with
formulas for log-location mu and log-scale sigma.
Value
A drm_family object.
Details
The model is defined on the log response scale:
log(y) ~ Normal(mu, sigma^2). The fitted distributional parameter mu is
therefore the mean of log(y), not the arithmetic mean of y.
