The Journal of Statistics Education [4] points out an exception to the rule: In a data analysis course, a third moment formula calculates the skew. Consequently, some distributions can break the rule of thumb. The following distribution was made from a 2002 General Social Survey. Respondents st...

The resulting graph is a left-skewed distribution. This formula implies that approximately 5% of scientists produce about half of all papers and the others share the other half. On the other hand, the proportion of all contributors with only one publication is about 60%. Even though Lotka's ...
Skewness risk is the increased risk of turning up a data point of high skewness in a skewed distribution. Many financial models that attempt to predict the future performance of an asset assume a normal distribution. If the data are skewed, this model will always underestimate skewness risk in ...
Because of thinking only the number of numbers but not fitting function, it would be adequate to take further afield when calculating group numbers with empirical formula. We have proved the three theorems based on studying the normal distribution, and then reach the conclusion that there is a ...

The kurtosis values of the remaining log- return frequencies are smaller, but do not approach the kurtosis of the normal distribution (KU = 3). The results for skewness (λ) indicate, in general, the presence of negative skewness in the data. Twenty out of the twenty-eight estimated values...

If that is the case, than there can be no transformation that will lead to a normal distribution. In that case you could consider modeling the zero separately using -zip-. It is usually used for counts, but can also be used for continuous variables in a Quasi-likelihood kind of way, ...
