philion: Dose response data

philionR Documentation

Dose response data

Description

Four small experiments with the purpose of estimating the EC50 of a biological dose-response relation.

Usage

philion

Format

A data frame with 30 observations on the following 3 variables:

experiment

a numeric vector; codes 1 through 4 denote the experiment number.

dose

a numeric vector, the dose.

response

a numeric vector, the response (counts).

Details

These data were discussed on the R mailing lists, initially suggesting a log-linear Poisson regression, but actually a relation like y=y_{\rm max}/(1+(x/\beta)^\alpha) is more suitable.

Source

Original data from Vincent Philion, IRDA, Qu\'ebec.
