    Linear Algebra describes a very powerful method of solving linear equations by matrix method. Since in regression we need to solve for the coefficients of the regression line, matrix method can be used to this end. In this way, linear algebra can help perform linear regression.

    The correlation coefficient is a number between -1 and 1 which measures the degree to which two variables are linearly related. If there is perfect ...
