What are the Tests Frequentists Use?
Frequentist statistics utilizes a range of tests to draw conclusions and make inferences from observed data. These tests analyze different aspects of data and assess relationships between variables. Here are some of the main tests:
- T-tests: Used to compare the means of two groups and determine if they are significantly different from each other.
- Chi-squared tests: Used to test the association between categorical variables in a contingency table.
- Analysis of Variance (ANOVA): Used to compare means across two or more groups to determine if there is a significant difference between them.
- Regression analysis: Used to assess the relationship between a dependent variable and one or more independent variables.
- F-tests: Used to compare the fits of different statistical models to the same data.
- Z-tests: Similar to t-tests but used when the sample size is large and/or the population standard deviation is known.
- Correlation tests: Used to calculate the relationship’s strength and direction between two continuous variables.
- Goodness-of-fit tests: Used to assess how well an observed frequency distribution fits an expected distribution.
- Hypothesis tests: Used to assess the validity of a hypothesis about a population parameter based on sample data.
Frequentist vs Bayesian Approaches in Machine Learning
Frequentist and Bayesian approaches are two fundamental methodologies in machine learning and statistics, each with distinct principles and interpretations. Here, we will see how these two approaches differ.
