Goodness-of-Fit measures how well statistical models mirror actual observed data, crucial for accurate predictions.
This test scrutinizes observed vs. expected frequencies in categorical data, highlighting model-data congruence.
Specialized for small samples, this test compares your data's distribution to the normal benchmark.
Central to interpreting results, these metrics reveal the significance of the model-data discrepancy.
Rejecting the null hypothesis signals the model's inadequacy in representing the data accurately.
Assesses how well your continuous data align with a specified distribution, ideal for large samples.

Evaluates tail deviations in data distributions, perfect for extreme values or heavy tails.
An adaptation for small samples, checking normality and exponentiality without known parameters.
Compares observed with theoretical CDFs, offering insights less sensitive to tail deviations.
Evaluates fit of count data against expected distributions, vital for Poisson or binomial models.
Goodness-of-fit ensures models in healthcare, like diabetes prediction, are accurate and reliable.
In finance, these tests validate models predicting stock prices or portfolio risks.
Critical for models forecasting climate patterns or pollution levels, ensuring environmental safety.
