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=y_{\rm max}/(1+(x/\beta)^\alpha)
is
more suitable.
Original data from Vincent Philion, IRDA, Qu\'ebec.
