Chi-squared Distribution
In statistics, the chi-squared distribution is a probability distribution that is used to test the independence of two events. It is also used to test the goodness of fit of a model to a set of observed data. The distribution is characterized by a single parameter, the degrees of freedom, which determines the shape of the distribution. The chi-squared distribution is widely used in hypothesis testing, particularly in the fields of biology, physics, and engineering. It is also used in machine learning and data science for feature selection and model evaluation.
