Web3 de fev. de 2024 · If a distribution has positive kurtosis, it is said to be leptokurtic, which means that it has a sharper peak and heavier tails compared to a normal distribution. This simply means that fewer data values are located near the mean and more data values are located on the tails. WebSkewness and kurtosis are two commonly listed values when you run a software’s descriptive statistics function. Many books say that these two statistics give you insights into the shape of the distribution. Skewness is a measure of the symmetry in a distribution. A symmetrical dataset will have a skewness equal to 0.
WebHigh kurtosis is most likely to imply a distribution fatter tailed than the normal, so some very high (+ or -) residuals. Even if there are many near zero, that is only the good news, and it is the possible bad news that …
WebGraphical methods include the histogram and normality plot. Statistically, two numerical measures of shape – skewness and excess kurtosis – can be used to test for normality. If skewness is not close to zero, then your data set is not normally distributed. To learn about statistical functions in MAQL, see our Documentation.

In probability theory and statistics, kurtosis (from Greek: κυρτός, kyrtos or kurtos, meaning "curved, arching") is a measure of the "tailedness" of the probability distribution of a real-valued random variable. Like skewness, kurtosis describes a particular aspect of a probability distribution. There are different ways to quantify kurtosis for a theoretical distribution, and there are corresponding ways of estimating it using a sample from a population.
