Detailed Description

A set of parameters for /aggregate/statistics/byrange.

Divides the given set into bins and calculates statistics of the values of a value-column in each bin. The bins are based on the values of a given binning-column. The statistics that may be requested are mean, stdv (standard deviation), variance, skew, kurtosis, sum, min, max, first, last and weighted average. In addition to the requested statistics the count of total samples in each bin is returned. This counts vector is just the histogram of the column used to divide the set members into bins. The weighted average statistic requires a weight_column to be specified in <member name="options">. The weighted average is then defined as the sum of the products of the value column times the weight column divided by the sum of the weight column.
There are two methods for binning the set members. In the first, which can be used for numeric valued binning-columns, a min, max and interval are specified. The number of bins, nbins, is the integer upper bound of (max-min)/interval. Values that fall in the range [min+n*interval,min+(n+1)*interval) are placed in the nth bin where n ranges from 0..nbin-2. The final bin is [min+(nbin-1)*interval,max]. In the second method, <member name="options"> bin_values specifies a list of binning column values. Binning-columns whose value matches the nth member of the bin_values list are placed in the nth bin. When a list is provided the binning-column must be of type string or int.

Constructs an AggregateStatisticsByRangeRequest object with the specified parameters.

Parameters

table_name	Name of the table on which the ranged-statistics operation will be performed.
select_expression	For a non-empty expression statistics are calculated for those records for which the expression is true.
column_name	Name of the binning-column used to divide the set samples into bins.
value_column_name	Name of the value-column for which statistics are to be computed.
stats	A string of comma separated list of the statistics to calculate, e.g. 'sum,mean'. Available statistics: mean, stdv (standard deviation), variance, skew, kurtosis, sum.
start	The lower bound of the binning-column.
end	The upper bound of the binning-column.
interval	The interval of a bin. Set members fall into bin i if the binning-column falls in the range [start+interval``i, start+interval``(i+1)).
options	Map of optional parameters: additional_column_names A list of comma separated value-column names over which statistics can be accumulated along with the primary value_column. bin_values A list of comma separated binning-column values. Values that match the nth bin_values value are placed in the nth bin. weight_column_name Name of the column used as weighting column for the weighted_average statistic. order_column_name Name of the column used for candlestick charting techniques.
