variance
variance(a, b, c, ...)
variance(A)
variance(A, dimension)
variance(A, normalization)
variance(A, dimension, normalization)
Compute the variance of all values. Optional parameter normalization can be "unbiased" (default), "uncorrected", or "biased".
Try it yourself:
| $1 | variance(2, 4, 6)
| |
| $2 | variance([2, 4, 6, 8])
| |
| $3 | variance([2, 4, 6, 8], "uncorrected")
| |
| $4 | variance([2, 4, 6, 8], "biased")
| |
| $5 | variance([1, 2, 3; 4, 5, 6])
