Description Usage Arguments Value Examples
Determine the effective dose for a specified percent effect from a fitted probit regression model.

|
pct |
A numeric scalar of the effect (as a percent) for which to estimate the effective dose. |
pfit |
An object of class |
alpha |
A numeric scalar, the significance level used to generate
100*(1 - |
logbase |
A numeric or logical scalar, the base of the log transformation used for
dose in |
A numeric vector of length three, the effective dose and the lower and
upper 100*(1 - alpha
)% confidence limits.
