Standard deviation of slope estimate. Standard deviation of intercept estimate. Standard deviation of the intercept estimate multiplied by the chi-square test statistic weighted sum of squares divided by degrees of freedom. Weighted average of x observations at final iteration. Weighted average of y observations at final iteration.
Root mean square error in the x-direction.
XRES Real vector dimensioned at least N The x residuals. All calculations are done in single precision. The routine is coded in standard Fortran 77. Fitting straight lines when both variables are subject to error. Least-square fitting of a straight line.
