Four sigmoid growth functions and two exponential functions are described. Relevant values are calculated for estimated functions and presented in tables. Six examples are presented and interpreted. Estimated functions and contour plots for the rate of relative growth are shown in figures. Functions are estimated with SAS 6.12 and STATISTICA 5.0.
