Module stat
Stable statistics accumulator for n-arrays.
Functions
| acc (item) | add the item to the incremental mean and variance and increase the iteration count |
| mean () | get the incremental mean value |
| var () | get the incremental variance (sigma^2) |
| iter () | get the iteration count |
| set (new_m, new_v, new_i) | set the statistics and counter |
| reset () | reset counter and clear statistics |
