Functionality

List Statistics node computes various statistical quantities for the input values.

Inputs

The Data input is expected to be a list of integers / floats or list of lists of integers / floats. All inputs are vectorized.

Parameters

The Function parameter allows to select the statistical function to compute the corresponding statistical quantity for the input values.

  • All Statistics

  • Sum

  • Sum Of Squares

  • Sum Of Inverse

  • Product

  • Average

  • Geometric Mean

  • Harmonic Mean

  • Variance

  • Standard Deviation

  • Standard Error

  • Root Mean Square

  • Skewness

  • Kurtosis

  • Count

Average

The statistical function applied to the input values.

For “All Statistics” selection the node computes and outputs the statistical quantities for all the statistical functions along with their corresponding names.

For “Selected Statistics” selection the node computes and outputs the statistical quantities for the selected statistical functions along with their corresponding names.

Percentage

Float

0.75

The percentage value for the percentile function. [1]

Normalize

Boolean

False

Flag to normalize the histogram bins to the given normalize size. [2]

Bins

Int

10

The number of bins in the histogram. [2]

Size

Float

10.00

The normalized size of the histogram.[2]

Notes: [1] : The Percentage input socket is available only for the Percentile function. [2] : The Normalize setting and the Bins and Size input sockets are available only for the Histogram function.

Extra Parameters

The Property Panel contains additional settings to configure the statistics drawn in the node editor: font, text color, text scale and floating point precision of the displayed statistics, the x/y offset of the displayed statistics relative to the node and a setting for toggling the statistics names between full names and abbreviations.

The fonts used for this node are monospace fonts for best text alignment.

Outputs

  • Name(s) The name(s) of the statistical value(s) computed corresponding to the selected statistical function.

  • Value(s) The statistical quantity of the input values corresponding to the selected function. For a vectorized input the output values are a series of quantities corresponding to the selected function.

When “All Statistics” is selected the Names and Values outputs will list the names and the corresponding values for all the statistical functions.
