Web27 jan. 2024 · Mahalanobis distance is used to calculate the distance between two points or vectors in a multivariate distance metric space which is a statistical analysis involving several variables. To start with we need a dataframe. Example: Create dataframe R set.seed(700) score_1 <− rnorm(20,12,1) score_2 <− rnorm(20,11,12) score_3 <− … WebCompute the squared Mahalanobis distances of given observations. Parameters: Xarray-like of shape (n_samples, n_features) The observations, the Mahalanobis distances of the which we compute. Observations are assumed to be drawn from the same distribution than the data used in fit. Returns: distndarray of shape (n_samples,)
