The F-Test for Regression Analysis

Towards Data Science

The F-test, when used for regression analysis, lets you compare two competing regression models in their ability to “explain” the variance in the dependent variable.

Comparison of F-test and mutual information

Scikit-learn Examples

Comparison of F-test and mutual information This example illustrates the differences between univariate F-test statistics and mutual information. We consider 3 features x_1, x_2, x_3 distributed unifo...

Uncovered Interest Rate Parity and F-test on Regression Parameters using R

R-bloggers

This post explains how to perform the F-test of joint parameter restrictions on a linear regression model. As an example, we use the data in Chen and Tsang (2013), who introduce so called relative Nel...

The Lesser-Known, AWESOME Signs Test

Towards Data Science

We are all familiar with the T-test, maybe the F-test, and maybe even some others like Wilcox rank-sum tests and things of that nature. There are a lot of statistical tests, some of which we all use…

The Most Important Statistical Test

Towards Data Science

The likelihood ratio test (LRT) “unifies” frequentist statistical tests. Brand-name tests like t-test, F-test, chi-squared-test, and so on are specific cases (or even approximations) of the LRT…

How to Implement the Frechet Inception Distance (FID) for Evaluating GANs

Machine Learning Mastery

Last Updated on October 11, 2019 The Frechet Inception Distance score, or FID for short, is a metric that calculates the distance between feature vectors calculated for real and generated images. The ...

Test Fixtures and a Decorator for Explicit Waits

Test-Driven Web Development with Python

Now that we have a functional authentication system, we want to use it to identify users, and be able to show them all the lists they have created. To do that, we’re going to have to write FTs that ha...

Sarcasm Classification (Using FastText)

Towards Data Science

FastText is a library created by the Facebook Research Team for efficient learning of word representations and sentence classification. It has gained a lot of attraction in the NLP community…

Fully Mastering Fisher’s Exact Test for A/B Testing

Towards Data Science

While Fisher’s exact test is a convenient tool for A/B testing, the idea and results of the test are often hard to grasp and difficult to explain. Whether to struggle with the Hypergeometric distribu...
