Probability of type i error calculator
Webb20 juni 2024 · Simulate bivariate data with a strong correlation, rho=0.8. Test the hypothesis that H0: rho=0. Thus, you are simulating data under the alternative hypothesis which is why you get the result of 0.864. This is essentially your power for that particular alternative. You could do the following instead: sigma <- matrix (c (1,0,0,1),2,2) mu <- c (0 ... WebbControlling the FWER. Some tests, especially in the sciences, can be rerun tens of thousands of times.

I know that a Type 1 error is the probability of rejecting the null hypothesis when it is actually true. However, I am not sure what is meant by a two-tailed Type 1 error rate. Does the 'two-tailed' refer to the fact that the hypothesis test used is two-sided?
The probability of making a Type I error is the significance level, or alpha (α), while the probability of making a Type II error is beta (β). These risks can be minimized through careful planning in your study design. Example: Type I vs Type II error You decide to get tested for COVID-19 based on mild symptoms.
