## Description

A lot of real world measurements are first study by collecting samples. When we identify the distribution they belong to, we can simulate the data with random number generated from that known distribution. <br><br>This tool allows you to configure the parameters of a selected distribution. Click the triggering icon to generate the data and display the histogram. By repeating the generating runs, we can get a better visual feel of the variation of sampling from the same distribution as if you collect real life sample measurements. This process is the well known Monte Carlo Simulation.<br><br>Similarly you can lookup probabilities and it&#39;s inverse.  It also display the distribution and input level.<br><br>Support linear, logistic regression and residual plot. Cox regression with survival curve.<br><br>Support plotting on scatter, principal component, multidimensional scaling, Kaplan-Meier curve and 3D plot with rotation
