Webb27 nov. 2024 · 1 Answer. When a variable X has a Normal distribution with mean μ and standard deviation σ > 0, we say that Z = e X has a Lognormal ( μ, σ) distribution. The laws of logarithms show that μ (an additive location parameter for the Normal family of distributions) determines the scale of Z. Because the skewness of a variable does not … WebbCalculation of Skewness can be done as follows – Skewness: (sum of the Deviation Cube)/ (N-1) * Standard deviation’s Cube. = (106374650.07) / (29 * 6768161.24) = 0.54 Hence, the value of 0.54 tells us that the distribution data skew from the normal distribution. Advantages Skewness is better for measuring the performance of investment returns.
