一个人计算每次试验中一个事件的发生次数，直到发生了m次成功，并指定比率x=m/n，其中n是事件的总数。本文证明了x的频率的无偏估计是m[长虚线]1/n[长虚线]1，并且它的方差是近似的。等于m(n[长划线]m)/n2(n[长划线]1)。一个人计算每次试验中一个事件的发生次数，直到发生m次成功，并指定比率x=m/n，其中n是事件的总数。本文证明了x的频率的无偏估计是m[长虚线]1/n[长虚线]1，并且它的方差是近似的。等于m(n[长划线]m)/n2(n[长划线]1)。
A person counts the occurrences of an event per trial until m successes have occurred and designates the ratio x = m/n, where n is the total number of events. This article proves that an unbiased estimate of the frequency of x is m[long dash]1/n[long dash]1 and that its variance is approx. equal to m(n[long dash]m)/n2(n[long dash]1).A person counts the occurrences of an event per trial until m successes have occurred and designates the ratio x = m/n, where n is the total number of events.
