The Statistics::LineFit module does weighted or unweighted least-squares
|
|
line fitting to two-dimensional data (y = a + b * x). (This is also
|
|
called linear regression.) In addition to the slope and y-intercept, the
|
|
module can return the square of the correlation coefficient (R squared),
|
|
the Durbin-Watson statistic, the mean squared error, sigma, the t
|
|
statistics, the variance of the estimates of the slope and y-intercept,
|
|
the predicted y values and the residuals of the y values.
