Kendall Correlation vs Pearson Correlation
Developers should learn Kendall correlation when working with data that is ordinal, has ties, or contains outliers, such as in ranking systems, survey responses, or non-normal datasets meets developers should learn pearson correlation when working with data-driven applications, such as in machine learning for feature selection, data preprocessing, or exploratory data analysis to identify relationships between variables. Here's our take.
Kendall Correlation
Developers should learn Kendall correlation when working with data that is ordinal, has ties, or contains outliers, such as in ranking systems, survey responses, or non-normal datasets
Kendall Correlation
Nice PickDevelopers should learn Kendall correlation when working with data that is ordinal, has ties, or contains outliers, such as in ranking systems, survey responses, or non-normal datasets
Pros
- +It is particularly useful in machine learning for feature selection, evaluating model performance on ranked outputs, and in data analysis tasks where monotonic relationships need to be quantified without parametric assumptions
- +Related to: statistics, data-analysis
Cons
- -Specific tradeoffs depend on your use case
Pearson Correlation
Developers should learn Pearson Correlation when working with data-driven applications, such as in machine learning for feature selection, data preprocessing, or exploratory data analysis to identify relationships between variables
Pros
- +It is essential in fields like finance for portfolio analysis, in bioinformatics for gene expression studies, and in social sciences for survey data interpretation, helping to inform model building and hypothesis testing
- +Related to: statistics, data-analysis
Cons
- -Specific tradeoffs depend on your use case
The Verdict
Use Kendall Correlation if: You want it is particularly useful in machine learning for feature selection, evaluating model performance on ranked outputs, and in data analysis tasks where monotonic relationships need to be quantified without parametric assumptions and can live with specific tradeoffs depend on your use case.
Use Pearson Correlation if: You prioritize it is essential in fields like finance for portfolio analysis, in bioinformatics for gene expression studies, and in social sciences for survey data interpretation, helping to inform model building and hypothesis testing over what Kendall Correlation offers.
