WebMar 19, 2011 · Normally with a regression model in R, you can simply predict new values using the predict function. The problem with a binomial model is that the model estimates the probability of success or failure.

Remember that, ‘odds’ are the probability on a different scale. Here is the formula: If an event has a probability of p, the odds of that event is p/ (1-p). Odds are the transformation of the probability. Based on this formula, if the probability is 1/2, the ‘odds’ is 1. preferred business partner
