WebFor the geometric distribution the expected value is calculated using the definition. Although the sum is pretty difficult to calculate, the result is very simple: E [X] = sum x*p* (1-p) x-1 = 1/p. This is also very intuitive. If something happens with probability p, you expect to need 1/p tries to get a success. WebThis distribution has two key parameters: the mean (µ) and the standard deviation (σ) which plays a key role in assets return calculation and in …
