Univariate Outlier Detection Based On Normal Distribution

Detection of Univariate Outlier Based On Normal DistributionData involving only one attribute or variable are called univariate data. For simplicity, we often choose to assume that data are generated from a normal distribution. We can then learn the parameters of the normal...

Mahalanobis Distance using R code

Mahalanobis distance is one of the standardized distance measure in statistics. It is a unit less distance measure introduced by P. C. Mahalanobis in 1936. Here i have using R code and one example for multivariate data sets to find the Mahalanobis distance. Mahalanobis Distance Formula: ${{D}^{2}}=(x-\mu {)}'\sum{^{-1}}(x-\mu )$ where, x - Number...
