  • Patent number: 8027897
    Abstract: Methods, systems, and computer program products are provided for optimizing financial performance. Time series data describing the financial performance generated by corresponding marketing investments is provided to configure an econometric model. Linear coefficients of the econometric model are adjusted in accordance with the qualitative factors received as inputs from experts. The econometric model is transformed into an aggregated non-linear econometric model that includes non-linear factors that cause the financial performance to change at a varying rate as a function of the marketing investments. An allocation of the marketing investments generated by the aggregated non-linear econometric model is adjusted by applying an optimization algorithm to provide an optimized financial performance.

  • Publication number: 20110184934
    Abstract: A method for compressing an initial dataset may be implemented on a data processing system. The method may include generating a group of bootstrap samples of wavelet coefficients from the initial dataset using a wavelet basis function. An average quantile of the group of bootstrap samples of wavelet coefficients may be determined. The group of wavelet coefficients may be compressed by deleting initial wavelet coefficients having magnitudes less than the coefficient cutoff value equal to the average quantile. The compressed group of wavelet coefficients and the wavelet basis function may be used to approximate the initial dataset.

  • Publication number: 20110010405
    Abstract: Sensor data is received from one or more sensors. The sensor data is organized within a hierarchy. The sensor data is organized within a hierarchy that is non-dyadic. A processor of a computing device generates a discrete wavelet transform, based on the sensor data and based on the hierarchy of the sensor data, to compress the sensor data. The sensor data, as has been compressed via generation of the discrete wavelet transform, is processed.

  • Publication number: 20100114794
    Abstract: Methods, systems, and computer program products are provided for quantifying financial impact of marketing investments. Time series data describing the financial performance generated by corresponding marketing investments that are made as a function of time is provided to configure an econometric model. The econometric model, which describes a linear relationship between the financial performance and the corresponding marketing investments, is transformed into an aggregated non-linear econometric model that includes non-linear factors causing the financial performance to change at a varying rate as a function of the marketing investments.

  • Publication number: 20100114648
    Abstract: Methods, systems, and computer program products are provided for incorporating qualitative factors into an econometric model. Time series data describing the financial performance generated by corresponding marketing investments that are made as a function of time is provided to configure an econometric model. The econometric model includes linear coefficients that define a linear relationship between the financial performance and the corresponding marketing investments. The linear coefficients are adjusted in accordance with the qualitative factors received as inputs from experts, thereby enabling the qualitative factors to be quantified into the econometric model.

  • Publication number: 20100114869
    Abstract: In a method for generating a query plan for estimating a number of unique entry counts of an attribute in a database, a sample of entries in the database is identified, at least one of a sampling percent and a coefficient of variance of the entries in the sample is identified, and a skewness of the entries in the sample is calculated. In addition, at least one of a plurality of estimators is selected based upon the skewness of the entries and at least one of the sampling percent and the coefficient of variance of the entries in the sample. Moreover, a query plan is generated from the selected at least one of the plurality of estimators. A query optimizer for performing the method is provided.
