| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | A parameter estimating method based on a logistic curve model with missing data is proposed. Since the model is described by an unequal step difference equation that has an exact solution, the method completely recovers parameters of the difference equation when data are on an exact solution curve. The method makes full use of data without wasting any data or generating plausible data for the missing data. It only requires regression analysis and a simple optimization technique and showed better fitting than two conventional methods for three actual datasets. | |
