Patent number: 10664555Abstract: A computing device provides distributed estimation of an empirical distribution function. A boundary cumulative distribution function (CDF) value is defined at a start of each region of a plurality of regions. An accuracy value is defined for each region. (a) First equal proportion bins are computed for a first sample of a first marginal variable using the defined boundary CDF value for each region. (b) Second equal proportion bins are computed for the first sample of the first marginal variable within each region based on the defined accuracy value for each region. (c) The computed second equal proportion bins are added as an empirical distribution function (EDF) for the first marginal variable. (d) (a) to (c) are repeated for each remaining sample of the first marginal variable. (e) (a) to (d) are repeated with each remaining marginal variable of a plurality of marginal variables as the first marginal variable.Type: GrantFiled: June 6, 2019Date of Patent: May 26, 2020Assignee: SAS Institute Inc.Inventor: Mahesh V.

Patent number: 10565085Abstract: Metadata received from each worker computing device describes EDF estimates for samples of marginal variables stored on each respective worker computing device. Combinations of the EDF estimates are enumerated and assigned to each worker computing device based on the metadata. A request to compute outcome expectation measure values for an outcome expectation measure is initiated to each worker computing device based on the assigned combinations. The outcome expectation measure values computed by each worker computing device are received from each respective worker computing device. The received outcome expectation measure values are accumulated for the outcome expectation measure. A mean value and a standard deviation value are computed for the outcome expectation measure from the accumulated, received outcome expectation measure values. The computed mean and standard deviation values for the outcome expectation measure are output to represent an expected outcome based on the marginal variables.Type: GrantFiled: June 6, 2019Date of Patent: February 18, 2020Assignee: SAS Institute, Inc.Inventor: Mahesh V.
