or outliers, in the data. If the kurtosis value is positive, it tells us that the distribution has a tall peak and the tails at each end are thick. When the kurtosis value is very high, it means that there are a lot of data points in these tails, far...

To calculate the Kurtosis value for a dataset in Python, use the kurtosis() method of scipy.stats library. It accepts a dataset and calculates the kurtosis (Fisher or Pearson) of the given dataset.SyntaxBelow is the syntax of kurtosis() method -...

Expressions for the measures of skewness and kurtosis are derived for the multivariate Laplace distribution. The kurtosis matrix is used in Independent Component Analysis (ICA) where the solution of an eigenvalue problem of the kurtosis matrix determines the transformation matrix of interest [A. ...
2. Older references often state that kurtosis is an indication of peakedness. This is not correct. Charles Charles the Kurtosis value on my data is above 2 (+3). i think it should be between negative and positive 2. how can I change it to obtain normality??
What does it indicate if the skewness and kurtosis value is given as …. and no value… can that be ignored or what can be done Reply Charles October 14, 2020 at 5:21 pm Sorry, but I don’t understand your question. Charles

Starting again with a normal distribution, moving scores from the tails and the center to the shoulders will decrease kurtosis. A uniform distribution certainly has a flat top, with γ 2 = −1.2 , but γ2 can reach a minimum value of −2 when two score values are equally probably and...
Let’s see the main three types of kurtosis. Mesokurtic: This is the normal distribution Leptokurtic: This distribution has fatter tails and a sharper peak. The kurtosis is “positive” with a value greater than 3 Platykurtic: The distribution has a lower and wider peak and thinner tails. Th...
