摘要：
In the human body, cells are all the time dividing and reproducing. Williams et Bjerknes suggested a model for the growth of abnormal cells in a plane. Abnormal cells are assumed to divide k times faster than normal cells. In this paper an unbiased minimum variance estimator of k is obtained and the estimates obtained from simulated growths are compared with the actual values. A method of estimating k from the crinkliness of a growth, as suggested by Mollison, is also considered.
