A METHOD FITTING THE LOGISTIC CURVE
逻辑斯谛曲线的一种拟合方法

The common methods to fit the Logistic Curve have some disadvantages that the obtained result is indeterminate and variant, and there is no objective standard to judge it. This paper provides an optimization method of enumeration, which is well reflected in our determination of the parameters K, a and r. The procedure is that we first utilize the digital computer to determine the parameters K, a and r, and then compare one after another by the objective standard of search as a result of our obtaining the mo...
