Thirty months ago (n = 30), $100 was invested and has grown to a value today of $175.00. The monthly returns were normally distributed with monthly standard deviation of 10.0%. Without the return data, based on finding and using the geometric (a.k.a., time weighted) return, which of the following is the best estimate of the arithmetic average monthly return of the series? 请问此题这个公式是哪来的?E[geometric average] = E[arithmetic average] - 0.5*variance 谢谢
