Further approximations for selection intensity.
Three new approximations are suggested for the standardized selection intensity, i. Two are simple functions of powers of b, the fraction selected. These improve on previous approximations by covering a broader range of selection intensities. A third approximation is developed using a rational polynomial. This gave accurate approximation, but simplicity was lost.
