Weighted Statistic
Collects a basic weighted statistical summary. If the observation or the weight is infinite or NaN, then the observation is not recorded and the number of missing observations is incremented. If the observed weight is negative or 0.0, then the observation is not recorded and the number of missing observations is incremented.

When a data point having the value of (Double.NaN, Double.POSITIVE_INFINITY, Double.NEGATIVE_INFINITY) are presented it is excluded from the summary statistics and the number of missing points is noted. If the weight is infinite or less than or equal to zero, then the data point should not be recorded. This method reports the number of missing points that occurred during the collection.
Returns an array with the statistics defined by index = statistic
s0 = "Count"; s1 = "Average"; s2 = "Minimum"; s3 = "Maximum"; s4 = "Weighted Sum"; s5 = "Sum of Weights"; s6 = "Weighted sum of squares"; s7 = "Last Value"; s8 = "Last Weight"; s9 = "Unweighted Sum"; s10 = "Unweighted Average";
Gets the sum of the observed weights.
Gets the weighted average of the collected observations.
Gets the weighted sum of observations observed.
Gets the weighted sum of squares for observations observed.
