Univariate and multivariate skewness and kurtosis calculation

Normality Evaluation of Empirical Data

How to use List of software

This is a web-based program to calculate the univariate and multivariate skewness and kurtosis. The distribution of each variable is also evaluated through histogram and normal Q-Q plot.

Follow these steps to complete the analysis:

1. Upload a data set, choose its file format, and specify any values that should be treated as missing.
2. Review the uploaded data and continue to select the variables to analyze. Select at least one numeric variable.
3. Run the analysis to view univariate and multivariate skewness and kurtosis, along with a histogram and normal Q-Q plot for each selected variable.
