lecture :: Degrees of freedom

Posted by Kipoong Kim

Degrees of freedom has been widely used over statistics, such as hypothesis testing, regression, regularization. I introduce the degrees of freedom with an example. When someone want to know what is the degrees of freedom in your class, I hope this example is somewhat good.

In wikipedia, the degrees of freedom is explained as follows.

In statistics, the number of degrees of freedom is the number of values in the final calculation of a statistic that are free to vary

Moreover, the degree of freedom also means the model complexity, i.e., the larger the degree of freedom is, the simpler model is.
