WebbIn the past decade, an intensive study of strong approximation of stochastic differential equations (SDEs) with a drift coefficient that has discontinuities in space has begun. In the majority of these results it is assumed that the drift coefficient satisfies piecewise regularity conditions and that the diffusion coefficient is globally Lipschitz continuous … WebbUsually this is 80% or 90% (i.e. type II error of 10-20%). For continuous data, find the standard deviation of the outcome measure. This could be achieved by a review of the literature.

A Type I error can be made only if the null hypothesis is true, while a Type II error can be made only if the null hypothesis is false.

Webb24 apr. 2024 · Type II Error. Not reject the null hypothesis when there is a significant effect (false negative). The p-value is pessimistically large. In this context, we can think of the significance level as the probability of rejecting the null hypothesis if it were true. That is the probability of making a Type I Error or a false positive. WebbSo one way to think about the probability of a Type I error is your significance level. Now, if your null hypothesis is true and you failed to reject it, well that's good. This we can write …
