Demo of built-in statistics functions
There are a number of built-in basic statistics functions, such as mean and variance. These take an array of numbers as argument and return a single Number value. To avoid confusion with other functions, they must always be prefixed with stat, as in stat.mean(arr), where arr is an array of Numbers.
- Standard deviation
- Standard error
- Sum of squared errors (i.e., sume of squared deviations from mean)
- Lowest value
- Highest value
- Difference between highest and lowest value
