beetles: Mortality of confused flour beetles

In binomTools: Performing diagnostics on binomial regression models

Description

Data from a study examining the response of confused flour beetles to increasing concentrations of gaseous carbon disulphide. After exposure for five hours the exact concentration of carbon disulphide was determined and the number of dead flour beetles were recorded. For each concentration of carbon disulphide duplicate batches of beetles were used.

Usage
