Confidence bands for a sigmoidal fit

Description

Calculates the confidence band for a fitted 'drc' model.

Usage

  confband(object, level = 0.95)

Arguments

object an object of class 'drc'.
level the confidence level, defaults to 0.95.

Details

Calls the predict.drc function from the 'drc' package. The confidence intervals are based on asymptotic normality.

Value

A list with the following components:

x the x values, i.e. cycle number.
clo the response values of the lower confidence limit.
cup the response values of the upper confidence limit.

Examples

m <- pcrfit(reps, 1, 2, l5())
###with 99 percent confidence interval
ci <- confband(m, level = 0.99)
print(ci)
###plotting the confidence bands
pcrplot(m, confband = 0.99)
