| fahad | It is the opposite of Z formula in the numerator and also replace mean with minum acceptable level of return denoted as RL. |
| bobert | It isn't the opposite of the z-formula. z-value = (X-mean) / std dev. SFRatio = (Rp-RL) / std dev. Both formulas look to get an answer that is relative to standard deviation units. Therefore on a normal distribution, you use the SFRatio as a z-value to determine the F(X) |
