# Call exported routine on List-of-List of data (each nested list - row - corresponds to a set of observations. In void-context it prints a report to STDOUT.
# In LIST-context the routine returns an ARRAY reference of the coefficients and R^2.
my ($Array_ref_of_coefficients, $R_sq) = linear_regression($d);
The general purpose of multiple regression is to gain information about the relationship between several independent
variables (x_i) and a dependent variable (y). The procedure involves fitting an equation of the form:
y = b_o + x_1 * b_1 + x_2 * b_2 +... ... x_n * b_n
This is a minimal implementation of least squares procedure that accepts a List-of-Lists in which each nested list
corresponds to a single set of observations. The single exported routine returns the coefficients (b_i) and R^2.
