Web19 aug. 2009 · "Kurtosis greater than three (>3), which is the same thing as saying “excess kurtosis > 0,” indicates high peaks and fat tails (leptokurtic). Kurtosis less than three (<3), which is the same thing as saying “excess kurtosis < 0,” indicates lower peaks. Financial asset returns are typically considered leptokurtic (i.e., heavy or fat-tailed)" Web5 jul. 2012 · For sample sizes of 2,000 or larger, this test statistic is compared to a chi-squared distribution with 2 degrees of freedom (normality is rejected if the test statistic is greater than the chi-squared value). The chi-square approximation requires fairly large sample sizes to be accurate.

Skewness - Overview, Types, How to Measure and Interpret

WebThe normal distribution shown below has a kurtosis of 3: A kurtosis greater than 3 means the tails are heavier than the normal distribution. In order to have more units in the extreme tails also means there must also be more units near the middle of the distribution. WebIt is important to note that JMP centers Kurtosis on 0, meaning you can differentiate between thin and thick tails based on whether the value is greater or less than 0. In other software, Kurtosis is centered on 3, so you differentiate between thin and thick tails based on whether the value is greater or less than 3. WebIt so happens that for the normal distribution, μ 4 = 3 σ 4 so β 2 = 3. The excess kurtosis usually denoted by γ 2 is γ 2 = β 2 ( Normal) − 3. Care … small company meaning as per companies act
