PHP k-means Algorithm Data Miner: I need to segments all object into appropriate number of cluster

This package can find nearest neighbor of a set of location points.

It takes a set of geographic points given their latitude and longitude and it determine the nearest neighbor of another given point.

It can also generate an image that visualizes that renders the points and the areas they form as triangles.

This class can compute statistics on a set of values.

It takes an array of values and can computes the mean, median, mode, variance, standard deviation, coefficient of variation, skewness, and Kurtosis, covariance, correlation, and regression analysis, paired and unpaired t-Test including calculate the probability of null hypothesis, normal distribution, student t-distribution one and two tailed, F distribution, chi-square test or contingency tables (A/B testing), analysis of variance (ANOVA), Shannon and Simpson diversity index, moving average, hierarchical and k-mean clustering, boxplot, histogram, normal Q-Q plot, ternary plot, "1224" ranking, standardize.
