Consider a set of independent tests, each of these to test a certain null hypothesis , . For each test, a significance level , i.e., a p-value, is obtained. All these p-values can be combined into a joint test whether there is a global effect, i.e., if a global null hypothesis can be rejected. WebJan 9, 2024 · Fisher’s Linear Discriminant, in essence, is a technique for dimensionality reduction, not a discriminant. For binary classification, we can find an optimal threshold t and classify the data accordingly. For multiclass data, we can (1) model a class conditional distribution using a Gaussian. dana hetland funeral home

WebI will get two complementing p-vals (e.g., 0.995 & 0.005 ). Interestingly, combining the two brings about a significant p -value in the Fisher test: p = 0.0175. This is weird because I could have chosen the exact opposite test ( μ > 0) and sampled results - and still get p = 0.0175. It's almost as if the Fisher test does not take the direction ...
