Abstract: A computer-implemented method and computer program product for selecting a portfolio weight (subject to specified constraints) for each of a plurality of assets of an optimal portfolio. A mean-variance efficient frontier is calculated based on input data characterizing the defined expected return and the defined standard deviation of return of each of the plurality of assets. Multiple sets of optimization inputs are drawn from a distribution of simulated optimization inputs consistent with the defined expected return, the defined standard deviation of return of each of the plurality of assets and then a simulated mean-variance efficient frontier is computed for each set of optimization inputs. A meta-resampled efficient frontier is determined as a statistical mean of associated portfolios among the simulated mean-variance efficient frontiers, and a portfolio weight is selected for each asset from the meta-resampled efficient frontier according to a specified investment objective.

Abstract: A system for delivering selective VCR control codes to programmable settop terminals over a CATV communication system includes a headend for storing and transmitting VCR control code information to the settop terminals and a plurality of settop terminals for receiving the control codes. The CATV communication system delivers the VCR control codes to individual subscribers within the vertical blanking interval of one of the broadcast channels or over a control data channel. A set-up procedure is required for each VCR to determine the appropriate set of VCR control codes. Upon determining the specific type of VCR the subscriber has, the VCR control codes transmitted through the CATV system are stored in the settop terminal in non-volatile memory. Since the settop terminal only stores the VCR control codes for a single type of VCR, memory requirements are minimized.
