Web13 de abr. de 2024 · Very roughly, the rationale for the approximate chi-squared distribution is that we could look at the X i as being Poisson events each with mean μ = λ = 100 and variance σ 2 = λ = 100. Standarizing, we have Z i = X i − μ σ ∼ a p r x N o r m ( 0, 1). If the Z i were independent, then Q = ∑ i = 1 6 Z i 2 would be approximately chi ...

Web2 de mai. de 2024 · Key Takeaways. Skewness is a statistical measure of the asymmetry of a probability distribution. It characterizes the extent to which the distribution of a set of values deviates from a normal distribution. Skewness between -0.5 and 0.5 is symmetrical. Kurtosis measures whether data is heavily left-tailed or right-tailed.
