Goodness of Fit

Exploratory security analytics for anomaly detection

“…Parametric techniques are useful when there is some evidence or knowledge about the underlying distribution of the data. For example, if the median ij m is stable and centered in the interquartile range ij iqr , it is possible that data might be modeled through a Gaussian distribution [37], although further analyses would be required, such as χ 2 goodness-of-fit test [30,47,48]. Other popular parametric distributions are Gamma and Long-tail.…”
