1 2 {{alias}}() 3 Returns an accumulator function which incrementally computes a geometric 4 mean. 5 6 If provided a value, the accumulator function returns an updated geometric 7 mean. If not provided a value, the accumulator function returns the current 8 geometric mean. 9 10 If provided `NaN` or a value which, when used in computations, results in 11 `NaN`, the accumulated value is `NaN` for all future invocations. 12 13 If provided a negative value, the accumulated value is `NaN` for all future 14 invocations. 15 16 Returns 17 ------- 18 acc: Function 19 Accumulator function. 20 21 Examples 22 -------- 23 > var accumulator = {{alias}}(); 24 > var v = accumulator() 25 null 26 > v = accumulator( 2.0 ) 27 2.0 28 > v = accumulator( 5.0 ) 29 ~3.16 30 > v = accumulator() 31 ~3.16 32 33 See Also 34 -------- 35
