Unbiased Estimation and Application of Parameters of Power and Exponential Functions

An estimate method of one kind of nonlinear function, power function and the exponential function is given in this article. With such method, the residual sum of squares which is obtained by computing the parameters of exponential function and power function is much smaller than that of linear method. It is closer to the result obtained by using Gauss Newton inference method, and much simpler than usual nonlinear regression inference method.
