Operators in python play very important role to compute mathematical, relational or logical expression. Operators in Python are tokens and when they apply on variables they provoke some computation. I-Unary Operators- These operators require only one variable. Examples- + (Unary Plus) – (Unary Minus) not ( Negation) ~ ( Bit-wise Negation) […]

Chi Square Distribution Chi square variate is a square of a normal variate having 1 degree of freedom and chi square distribution is a special case of Gamma distribution. If X is following normal distribution N(μ, σ) then Z=((X-μ)/σ)2 is a chi-square variate with 1 degree of freedom. The generalized form of chi-square variate is

Gamma function and Gamma Probability Distribution Gamma function and Gamma probability density both are very important concepts in mathematics and statistics. Furthermore, understanding Gamma function and Gamma probability density helps to understand chi-square distribution which plays very important role in machine learning. Especially, in Decision Tree Learning Chi-Square distribution used. In this post, I will
