Standard deviation of probability density
WebbTo find the density function fY(y) of Y, one strategy is to find the cumulative distribution function FY(y), and then differentiate. Note that Y is always positive, so FY(y) = 0 if y ≤ 0. Now suppose that y > 0. Then FY(y) = Pr (Y ≤ y) = Pr (eX ≤ y) = Pr (X ≤ lny). Thus FY(y) = ∫lny − ∞f(x)dx. To find the density, differentiate. WebbThe standard deviation of the distribution. Cumulative Required. A logical value that determines the form of the function. If cumulative is TRUE, NORM.DIST returns the cumulative distribution function; if FALSE, it returns the probability density function. Remarks If mean or standard_dev is nonnumeric, NORM.DIST returns the #VALUE! error …
