Kurtosis for normal distribution

WebApr 12, 2024 · You can also use numerical methods, such as tests of normality (e.g., Kolmogorov-Smirnov, Shapiro-Wilk) and measures of skewness and kurtosis, to quantify the deviation from normality. WebThe kurtosis of a probability distribution of a random variable x is defined as the ratio of the fourth moment μ 4 to the square of the variance σ 4, i.e., Kurtosis is primarily a measure of the heaviness of the tails of a distribution. The normal distribution has a kurtosis equal to 3.

WebThe general formula for the normal distribution is. f ( x) = 1 σ 2 π ⋅ e ( x − μ) 2 − 2 σ 2. where. σ (“sigma”) is a population standard deviation; μ (“mu”) is a population mean; x is a value or test statistic; e is a mathematical constant of roughly 2.72; π (“pi”) is a mathematical constant of roughly 3.14. WebKurtosis is a measure of how differently shaped are the tails of a distribution as compared to the tails of the normal distribution. While skewness focuses on the overall shape, Kurtosis focuses on the tail shape. Kurtosis is defined as follows: does dazn have nfl sunday ticket https://honduraspositiva.com
