Before applying the Box-Cox transformation, it is crucial to consider its implications on model assumptions, interpretation, and hypothesis testing. This article explores 12 critical questions you should ask yourself before using the transformation.
This article delves into the Chi-Square test, a fundamental tool for analyzing categorical data, with a focus on its applications in goodness-of-fit and tests of independence.
Machine learning is transforming climate science, offering powerful predictive tools for forecasting extreme weather, rising sea levels, and biodiversity shifts.
Heteroscedasticity can affect regression models, leading to biased or inefficient estimates. Here’s how to detect it and what to do when it’s present.
Explore the role of data science in predictive maintenance, from forecasting equipment failure to optimizing maintenance schedules using techniques like regression and anomaly detection.
One-way and two-way ANOVA are essential tools for comparing means across groups, but each test serves different purposes. Learn when to use one-way versus two-way ANOVA and how to interpret their results.
The multiple comparisons problem arises in hypothesis testing when performing multiple tests increases the likelihood of false positives. Learn about the Bonferroni correction and other solutions to control error rates.
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.
