Abstract: York 2 is a linear regression program that allows for errors in both X and Y and also for positive or negative correlation of the X and Y errors. The program accepts errors for each value of X and Y. If the errors are uncorrelated, the correlation coefficient (-1 <= R <= 1) may be set to zero. Input may be from the keyboard, a file, or paper tape, and the program has a variety of data editing features. Output consists of the slope, the intercept, the coordinates of the centroid, and six statistical parameters. The program uses the "least squares cubic" method of D. York, University of Toronto (York, 1969). The mathematics are identical to DECUS No. FOCAL8-315.
