Key Points Non-parametric tests are used when standard assumptions are not available. These tests don’t rely on distributions, often using real-world data instead. These tests are simple to implement, ...

Key Points The Wilcoxon Rank Sum Test is a non-parametric means of comparing data between two sets. It operates as a useful alternative to the 2-sample t-test. The Wilcoxon Rank Sum Test sometimes ...

Non-parametric tests or distribution free methods do not, and are used when the distributional assumptions for a parametric test are not met. While this is an advantage, it often comes at a cost of ...

The Wilcoxon signed rank test, which is also known as the Wilcoxon signed rank sum test and the Wilcoxon matched pairs test, is a non-parametric statistical test used to compare two dependent samples ...

Course TopicsLinear models, generalized linear models, and nonlinear models are examples of parametric regression models because we know the function that describes the relationship between the ...
