%X The traditional methods for fitting the logistic curve are found to have some weak points and can not be applied to all kinds of data.A new method,two-paired points method for estimating K value was therefore proposed.A group of 4 observed points arranged in two pairs with a same time interval is used for calculating an estimate-value of K,the upper asymptotic value of the curve? many estimate-values of K are thus obtained with all of such 4 points and the expectation value of these K estimate-values is thu...
