    摘要： A computing device determines one or more first degree correlations based on valuation information. The computing device determines one or more important variables based on at least a comparison between the absolute value of the one or more first degree correlations to a first threshold value. The computing device determines a valuation function based on at least one or more of the determined one or more important variables.

    摘要： A computer system may include a processor and a memory coupled thereto. The memory may include a database. The processor may be configured to randomly split the database into sub-databases and applying a database query to the sub-databases. The processor may also be configured to generate respective estimated query response values for each sub-database based upon applying the database query, calculate a median of the estimated query response values, and generate a probability distribution based upon the estimated query response values and the calculated median. The processor may further be configured to select a final estimated query response value based upon the probability distribution.
