histogram

Readonly iqr

iqr: number

inter quantile range (q3 - q1)

Readonly items

items: readonly (number | (readonly number[]) | Set<number>)[]

max: number

maximum value in the given data

Readonly maxBin

maxBin: IBin<number>

maximal items in a bin

missing: number

number of missing values (NaN, null, undefined) in the data

Readonly outlier

outlier: readonly number[]

outliers that are outside of the whiskers on both ends

Readonly q1

q1: number

25% quantile

variance: number

variance

Readonly whiskerHigh

whiskerHigh: number

whisker / fence above the 75% quantile (upper one) by default is computed as the largest element that satisfies (e <= q3 + 1.5IQR && e >= q1)

Readonly whiskerLow

whiskerLow: number

whisker / fence below the 25% quantile (lower one) by default is computed as the smallest element that satisfies (e >= q1 - 1.5IQR && e <= q1)

[toPrimitive]

  • [toPrimitive](hint: "default"): string
  • [toPrimitive](hint: "string"): string
  • [toPrimitive](hint: "number"): number
  • [toPrimitive](hint: string): string | number

  • Converts a Stats object to a string.

    Parameters

    • hint: "default"

    Returns string

  • Converts a Stats object to a string.

    Parameters

    Parameters

    • hint: "number"

    Returns number

  • Converts a Stats object to a string or number.

    throws

    {TypeError} If 'hint' was given something other than "number", "string", or "default".

    Parameters

    • hint: string

      The strings "number", "string", or "default" to specify what primitive to return.

    Returns string | number

    A number if 'hint' was "number", a string if 'hint' was "string" or "default".
