Exercise

Factorial Designs: Generating Odds Ratios

The trial referred to in the previous exercise found no evidence to suggest that the effect of one supplement depended on whether the other was administered.

Using the fact.data dataset, we will now explore the infection odds ratios for each supplement while ignoring whether the other was administered, using the oddsratio.wald() function within the epitools package. This package and the fact.data dataset have been loaded for the session.

Instructions

Use the oddsratio.wald() function to generate the odds ratio for the effect of glutamine on infection.
