WebbThe standard deviation of a population is simply the square root of the population variance. For example, its use with the arithmetic mean (as mean ± SD) is misleading for data with a skewed distribution. This is because errors are no … WebbThe exponentially modified normal distribution is another 3-parameter distribution that is a generalization of the normal distribution to skewed cases. The skew normal still has a … Webb11 okt. 2024 · I have a simulation of normally distributed numbers with a mean of 76 and a standard deviation of 0, which describes a series of constant numbers with the value 76. To this simulation, I apply a function that also yields constants and, therefore, its skewness should be also NaN. Why, when I calculate their skewness, do I not get NaN but 1? bebe pram
