  • Anomalies of the magnitude of the bias of the maximum likelihood estimator of the regression slope 

    O'Driscoll, Diarmuid; Ramirez, Donald E. (Athens Institute for Education and Research, 2015)
    The slope of the best-fit line y h x x 0 1  ( )    from minimizing a function of the squared vertical and horizontal errors is the root of a polynomial of degree four which has exactly two real roots, one positive and ...
  • Geometric View of Measurement Errors 

    O'Driscoll, Diarmuid; Ramirez, Donald E. (Taylor and Francis, 2011)
    The slope of the best fit line from minimizing the sum of the squared oblique errors is the root of a polynomial of degree four. This geometric view of measurement errors is used to give insight into the performance of ...
