Abstract:
1. A computer-implemented method of determining a role for a data variable for use in data modeling of a physical process, comprising: identifying to a plurality of data nodes a set of data records containing data values assigned to each data node, a maximum number of levels to record in a sorted data structure at the data nodes, and the data node responsible for each of a plurality of variables; receiving for each variable from the data node responsible for the variable a plurality of unique data values for the variable, a count for each of the unique data values and an overflow count for the variable, wherein a number of unique data values does not exceed the maximum number of levels, wherein the data values, counts and overflow count have been generated at a plurality of data nodes by node data processors configured by data processing instructions to: wherein a role for a variable is determined based upon the unique data values, counts and overflow count for a variable.
