Webb19 feb. 2024 · The p-value tells us whether or not the results of the test are significant, but it doesn’t tell us the effect size of the test. There are three ways to measure effect size: Phi (φ), Cramer’s V (V), and odds ratio (OR). In this post we explain how to calculate each of these effect sizes along with when it’s appropriate to use each one. In statistics, the phi coefficient (or mean square contingency coefficient and denoted by φ or rφ) is a measure of association for two binary variables. In machine learning, it is known as the Matthews correlation coefficient (MCC) and used as a measure of the quality of binary (two-class) classifications, introduced by … Visa mer Although computationally the Pearson correlation coefficient reduces to the phi coefficient in the 2×2 case, they are not in general the same.

WebbI am a newbie to statistics and found this. In statistics, θ, the lowercase Greek letter 'theta', is the usual name for a (vector of) parameter (s) of some general probability distribution. A common problem is to find the value (s) of theta. Notice that there isn't any meaning in naming a parameter this way.
