Web10 jul. 2015 · You can perfectly use the mean p -value. Fisher’s method set sets a threshold s α on − 2 ∑ i = 1 n log p i, such that if the null hypothesis H 0 : all p -values are ∼ U ( 0, 1) holds, then − 2 ∑ i log p i exceeds s α with probability α. H 0 is rejected when this happens. Usually one takes α = 0.05 and s α is given by a quantile of χ 2 ( 2 n). WebThe p-value is a probability. For the pattern analysis tools, it is the probability that the observed spatial pattern was created by some random process. When the p-value is very small, it means it is very unlikely (small probability) that the observed spatial pattern is the result of random processes, so you can reject the null hypothesis.
