Abstract: YORK2 is a linear regression program that allows for errors

in both X and Y and also for positive and 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. 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). It requires 8K of core.
