The McDonald–Kreitman test is a statistical test often used by evolutionary and population biologists to detect and measure the amount of adaptive evolution within a species by determining whether adaptive evolution has occurred, and the proportion of substitutions that resulted from positive selection (also known as directional selection). To do this, the McDonald–Kreitman test compares the amount of variation within a species (polymorphism) to the divergence between s… Web1 mei 2024 · In this paper, we presented asymptoticMK, a new web-based tool for executing the asymptotic MK test.

WebThe Mann-Kendall Trend Test (sometimes called the MK test) is used to analyze time series data for consistently increasing or decreasing trends (monotonic trends). It is a non-parametric test, which means it works for all distributions (i.e. data doesn't have to meet the assumption of normality), but data should have no serial correlation. WebThe MK Test uses the following test statistic: where se = the square root of var . If there is no monotonic trend (the null hypothesis), then for time series with more than 10 …
