Small&Fast JavaScript library that attaches xtra methods for Arrays, including basic Descriptive Statistics functions
- issolid() boolean, check whether array is not sparse
- solid() new array without undefined and null values
- isNaN() boolean, check whether the at least one element of the array isNaN
- unique() new array with unique elements
- OR(other_array) new array with the elements of the union
- AND(other_array) new array with the elements of the intersection
- XOR(other_array) new array with the elements of the union without the elements of the intersection
- min() returns the min value
- max() returns the max value
- range() returns [min, max]
- sum() returns the sum of the items of the array
- stack() returns a new array with the stacked values of each item
- module() number, returns the module
- normalize() new array, each item divided by module
- mean(i) number, mean of the items i=(-1: harmonic, 0: geometric, 1: aritmetic, 2: quadratic,... n: n-mean)
- median() number
- freq() object, frequency of each value
- mode() new array, modes of the array
- P(i) number, Percentile_i
- variance() number
- pvariance() number, population variance
