In DoseResponse/bmd: Benchmark dose estimation for dose-response data

Pool-adjacent-violators monotonizing

Description

The function monotonizes a sequence of probabilities or means based on the pool-adjacent-violators algorithm.

Usage

function(formula,data,type) 

Arguments

formula	an object of class "formula" expressing dose-response relationship. Details of model specification are given under 'Details'
data	data frame containing the variables in the formula
type	character string specifying the type of data used in the model, "continuous" or "binomial" or "Poisson"

Details

For details on how the pool-adjacent-violators algorithm is defined see Silvapulle and Sen (2004).

Formula should be specified as in the form number/total ~ dose for binomial data and response ~ for continuous data.

Value

A vector containing the monotonized sequence.
