`x` |
a numeric vector, matrix or data frame. |

`na.rm` |
logical. Should missing values be removed? |

Skewness:

*\frac{\frac{1}{n} ∑_{i=1}^n (x_i-\overline{x})^3}{≤ft(\frac{1}{n} ∑_{i=1}^n (x_i-\overline{x})^2\right)^{3/2}}*

(excess) Kurtosis:

*\frac{\frac{1}{n} ∑_{i=1}^n (x_i - \overline{x})^4}{≤ft(\frac{1}{n} ∑_{i=1}^n (x_i - \overline{x})^2\right)^2} - 3*

The skewness/kurtosis values.
