WebTo reduce the Type I error probability, you can set a lower significance level. What are Type I and Type II errors? In statistics, a Type I error means rejecting the null hypothesis … WebIn general, the stochastic fluctuations contribute more to the uncertainty than the initial state measurements. The variables coupling all major climate elements, such as CO 2 concentration of ocean surface temperature change are among the most sensitive variables to any kind of uncertainties.

WebType 2 (=β) is related with the power of the study, i.e. Power=1-β. It's the probability of finding the difference when it exists.
