The Fisher equation was derived in 1937 and takes the form [1] (1) ∂ u ∂ t = u ( 1 − u) + ∂ 2 u ∂ x 2, where u ( x, t) is a population density. Eq. (1) was also introduced and investigated in paper [2] in detail. This equation is often called as the Kolmogorov–Petrovsky–Piscunov equation. Exact solutions of Eq.

The key part of our method is to utilize the simultaneous perturbation stochastic approximation method to approximate the Hessian matrix from the gradient of the conditional expectation of the complete-data log-likelihood function. Key words: Fisher information matrix, EM algorithm, Monte Carlo, Simultaneous WebExample 3.3: Tukey vs. Bonferroni approaches. Here is an example we can work out. Let's say we have 5 means, so a = 5, we will let α = 0.05, and the total number of observations N = 35, so each group has seven observations and df = 30. If we look at the studentized range distribution for 5, 30 degrees of freedom, we find a critical value of 4.11.

Fisher's method combines extreme value probabilities from each test, commonly known as "p-values", into one test statistic (X ) using the formula $${\displaystyle X_{2k}^{2}\sim -2\sum _{i=1}^{k}\log(p_{i}),}$$ where pi is the p-value for the i hypothesis test. When the p-values tend to be small, the test … See more In statistics, Fisher's method, also known as Fisher's combined probability test, is a technique for data fusion or "meta-analysis" (analysis of analyses). It was developed by and named for Ronald Fisher. In its basic form, it is … See more In cases where the tests are not independent, the null distribution of X is more complicated. A common strategy is to approximate the null distribution with a scaled See more A closely related approach to Fisher's method is Stouffer's Z, based on Z-scores rather than p-values, allowing incorporation of study weights. It is named for the sociologist Samuel A. Stouffer. If we let Zi = Φ (1−pi), where Φ is the standard normal See more Dependence among statistical tests is generally positive, which means that the p-value of X is too small (anti-conservative) if the dependency is not taken into account.
