philion: Dose response data
In ISwR: Introductory Statistics with R

Description Usage Format Details Source References

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

philion

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).

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

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