Statistics in AI
Chi-Square Test
It is a statistical method that compares how the model compares against actual observed data.
Bayes’ Theorem
Bayes Theorem is a mathematical formula to determine conditional probability.
Bayes theorem relies on prior probability to generate posterior probability.
Correlation
It is a statistical measure that describes the degree to which two variables change together. Correlation coefficient such as Pearson’s correlation coefficient ranges from -1 to 1. 1 => Perfect positive correlation. This implies that if one variable increases then the other variable also increases proportionally. -1 => Perfect negative correlation. This implies that if one variable increases then the other variable also decreases proportionally. 0 => No linear correlation between variables.
Correlation does not imply causation.
