The Kolmogorov-Smirnov test is a powerful tool for assessing goodness-of-fit in non-parametric data. Learn how it works, how it compares to the Shapiro-Wilk test, and explore real-world applications.
Discover the fundamentals of Maximum Likelihood Estimation (MLE), its role in data science, and how it impacts businesses through predictive analytics and risk modeling.
Understand how causal reasoning helps us move beyond correlation, resolving paradoxes and leading to more accurate insights from data analysis.
Machine learning models degrade over time due to model drift, which includes data drift, concept drift, and feature drift. Learn how to detect, measure, and mitigate these challenges.
This article delves into mathematical models of inequality, focusing on the Lorenz curve and Gini coefficient to measure and interpret economic disparities.
Machine learning is often seen as a new frontier, but its roots lie firmly in traditional statistical methods. This article explores how statistical techniques underpin key machine learning algorithms, highlighting their interconnectedness.
Let’s examine why multiple imputation, despite being popular, may not be as robust or interpretable as it’s often considered. Is there a better approach?
AUC-ROC and Gini are popular metrics for evaluating binary classifiers, but they can be misleading on imbalanced datasets. Discover why AUC-PR, with its focus on Precision and Recall, offers a better evaluation for handling rare events.
Splines are powerful tools for modeling complex, nonlinear relationships in data. In this article, we’ll explore what splines are, how they work, and how they are used in data analysis, statistics, and machine learning.
Explore the differences between the Shapiro-Wilk and Anderson-Darling tests, two common methods for testing normality, and how sample size and distribution affect their performance.
