Calculation of Covariances of Variables Using MATLAB

Question

Please compute the covariances by using the dataset cov.mat 1. In this dataset, the data points are stored in a matrix X, where each row stands for one observation (datapoint) and each column stands for one attribute describing the data point.

Now we would like to know how those attributes are correlated? Please compute the covariance of each pair of those attributes. Based on the computed covariance, are they positively correlated, negatively correlated, or uncorrelated? You have to submit your MATLAB codes, which is a script file with .m extension. In this script file, you can add your computed covariances and conclusions as comments. What is the value of the covariance for each pair of the attributes and how they are correlated?

Summary

This question belongs to MATLAB software and discusses about application of MATLAB to probability and statistics to compute covariances of variables of given data.
