Arguments

    REJECTABLE
 
       Specifies if the function will supply a rejection code and message
       to the invalid feature and output it to the rejected port, or will
       fail upon being supplied invalid features.

       A feature can be rejected for the following reasons:
         - The feature has invalid geometry

   <[statistic] component list>

      A space-delimited list specifying the components for which each
      statistic will be calculated.

Description

   The @CalculatePointCloudStatistics function is used to calculate statistics
   on point cloud components.

   The following statistics may be calculated:

      - Minimum: The numerical minimum for numeric components, or the lexical
        minimum for string components.

      - Maximum: The numerical maximum for numeric components, or the lexical
        maximum for string components.

      - Range: The maximum minus the minimum. Undefined for string components.

      - Mean: The average value, calculated as the sum of values divided by
        the number of points. Undefined for string components.

      - Standard Deviation: The standard deviation as measured by the
        "nonbiased" or "n-1" method. Undefined for string components.

      - Sum: The sum of all values. Undefined for string components.

      - Median: The middle value when the values are listed in order if the
        number of points is odd, or the average of the two middle values if
        the number of points is even. For string components, the first middle
        value is always used.

      - Mode: The most frequent of all the values. If the dataset is bimodal
        (two or more values occur with the highest frequency) one of the
        values will be returned randomly.

      - Value Count: The number of points in the component that had non-missing,
        non-null values.

   Statistics will be stored as attributes on the feature. Attributes will be
   named "<component>.<statistic>", where statistic is one of the following:
      min, max, range, mean, stdev, sum, median, mode
   For example, if median was calculated for component "z", then an attribute
   named "z.median" would be added to the feature.

   Input features must contain point cloud geometries only.
