WebbWe can see that a probability threshold of 0.985 would sufficient control the type I error at the 5% level. The empirically calculated type I error from the simulations in 0.0544. Once we have determined the threshold required, we can calculate the power. WebbOne way to calculate the probability of committing a Type 1 error is by using the binomial theorem. This states that if there are n trials in an experiment and p successes out of those trials, then the probability of success on any given trial …
