On a non linear describing function for bio-data.
The behaviour and handling of a flexible three variable--parameter function is presented, which is suitable for unbiased regression analysis. The function is defined by an intercept, a slope or coefficient and an exponent on the independent variable. Analog and digital problems and solutions are defined. Handling is simple and the program is run without operator intervention. The range of curves include linear, convex, concave and asymptotic forms and can be extended to include sigmoid and parabolic forms. Some application results are presented for different situations.
