It doesn’t deal with causes or relationships (unlike regression) and it’s major purpose is to describe; it takes data, summarizes that data and finds patterns in the data. For MANOVA, our test statistic is and is computed as: = jWj jTj = jWj jB+ Wj. However, the currently used multivariate time‐independent stationary‐based risk analysis shows remarkable discrepancy with the multivariate time‐varying nonstationary one so that it underestimates the risk of drought occurrences (for all the frequent and extreme events) and both the drought severity and drought duration.

Multivariate statistics concerns understanding the different aims and background of each of the different forms of multivariate analysis, and how they relate to each other. Multivariate analysis (MVA) is based on the statistical principle of multivariate statistics, which involves observation and analysis of more than one statistical outcome variable at a time. Cyclic multivariate data is encountered in a variety of disciplines, including astronomy/astrophysics, medicine, time series analysis, global change studies, and production management.
