Chi-squared test for skewness in the standardised residualsGenaro Sucarrat
Goodness of fit test, The Jarque-Bera test is a goodness-of-fit test that measures if sample data has skewness and kurtosis that are similar to... The post Goodness of Fit Test- Jarque-Bera Test in R appeared first on finnstats.

In this context, the data was examined for normality and linearity. The skewness and kurtosis values must be between -2 and + 2 for the data to be considered normally distributed, according to Tabachnick and Fidell (2007). The normality assumption was met based on preliminary data ...

Implementation in R of the Bootstrapped Skewness-Adjusted t-test for testing long run mean abnormal returns as in "Improved Methods for Tests of Long-Run Abnormal Stock Returns" by Lyon et al (1999). Installation install_github('waissbluth/skewttest') library('skewttest') # Read the docs:...
Since all data were found to be in line with a normal distribution or slightly different from a normal distribution, with the value of skewness ranging from −1 to 1 and the value of kurtosis ranging from −3 to 3, the statistically significant differences in the posturometric parameters ...
Therefore, when presenting the results of Mann–Whitney tests, the median of each group should be presented along with a description of the skewness of each sample (e.g. with a box plot). The Mann–Whitney test also assumes that the two groups are independent. Where the measurements are ...
