WebbAnswer to Solved 1. Alpha is the probability of committing a Type I. This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts. WebbWe examine two types of problems to illustrate this. Unstructured testing problems arise typically (but not exclusively) when many outcomes are being measured. We consider the case of more than two hypotheses when a Bonferroni approach is being applied while for illustration we assume compound symmetry to hold for the correlation of all variables.
WebbTo calculate the probability of committing a Type I error, we first need to find the value of A. We know that fr(y) = (1/A)e-λy, where λ = 1 and y ≥ 0, so we can integrate fr(y) over the … Webb2 sep. 2024 · For example, a p-value of 0.02 reveals a 2% chance that you may reject the actual null hypothesis wrong. You can reduce this probability of committing a type 1 error achieving by lowering the value for p. For example, a p-value of 0.01 indicates that there may be a 1% chance of committing an error.

So then the type I error rate would be held to "at most α ", but not equal to α. On the other hand, there are (invalid) analysis strategies that lead to type I error rates that are greater than α, even when p < α (e.g., stepwise selection routines). georgetown street medicine outreachWebbThis problem has been solved!
