confintd is a generic function to compute confidence intervals for continuous functions
of the parameters in a fitted model. The function invokes particular methods which depend on the
class of the first argument.
confintd(object, expr, level = 0.95, ...)A matrix with columns giving the fitted values and lower and upper confidence limits for each derived parameter. The row names list the individual derived parameter expressions.
A fitted model object.
An expression or character vector that can be transformed to an expression
giving the function(s) of the parameters to be evaluated. Each expression should evaluate to a numeric scalar.
A numeric scalar between 0 and 1 giving the level of the derived parameter confidence intervals.
