In statistics, a type II error is accepting a null hypothesis that should be rejected. A type II error can occur if there is not enough power in statistical tests, often resulting from sample sizes that are too small. Increasing the sample size can help reduce the chances of committing a ...

If the probability of making a type 1 error is determined by “α”, the probability of a type 2 error is “β”. Beta depends on the power of the test (i.e the probability of not committing a type 2 error, which is equal to 1-β). There are 3 parameters that can affect the ...
The probability of making a Type II error can only be determined when values have been specified for the alternative hypothesis. The probability of making a type II error is denoted by β. 这一段种的第二句:只有当备择假设的值(检验统计量在此条件下的概率?)被指定后,第二类错误发生的概率才能...

A Monte Carlo simulation study was conducted to investigate Type I error rates and power of several corrections for nonnormality to the normal theory chi-square difference test in the context of evaluating measurement invariance via structural equation modeling. Studied statistics include the uncorrected...
CT3 eQTLs are detectable by either method if its baseline expression is high and in that case (2nd row and 2nd column of Fig. 1c) CSeQTL has much higher power than OLS, e.g., >80% power by CSeQTL vs. <20% power by OLS. OLS still has type I error inflation for CT2, to a...
The entries of μ1, the (q+2)-dimensional mean of the Z-statistics corresponding to the permutation-based gene test when the causal SNP is X1, are MathML In contrast, suppose that the correlation structure among SNPs is the same, that is, Cor(X1,Z i )=ρ i for 1≤i≤q, but ...
in the mouse posterior parietal cortex, carry a cell-type-specific error-correction signal for navigation. We obtained repeatable experimental access to these cells using an adeno-associated virus in which gene expression is driven by an enhancer that functions specifically in a subset of Sst cells...
