Excess kurtosis relative to normal distribution. High kurtosis means that
* the variance is due to infrequent, large deviations from the mean. Low
* kurtosis means that the variance is due to frequent, small deviations from
* the mean. The normal distribution is defined as having kurtosis of 0.
* Input must be an input range with elements implicitly convertible to double.
