WebDec 12, 2024 · 0.01. The p-value is the probability that the event occurs, assuming that H 0 is true; that is, the coin is fair (if we were in the universe where H 1 is true, then the p-value would be 1 for all the events). The occurrence of a tail once is quite regular, and for a fair coin, the probability of occurrence of Event 1 is 0.5. WebAug 3, 2024 · A logistic regression model provides the ‘odds’ of an event. 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.
