Rapid syndrome analysis apparatus and method

Abstract

In a computer; a computer readable medium for providing rapid syndrome analysis includes instructions for measuring a plurality of CUSUMs simultaneously and generating CUSUM data in response to an observed value. It also includes instructions for comparing the CUSUM data with a predetermined plurality of threshold values and instructions for generating a signal when the CUMSUM data exceeds any of the plurality of threshold values by a predetermined amount.

1 . In a computer; a computer readable medium for providing rapid syndrome analysis comprising:
 a) instructions for measuring a plurality of CUSUMs simultaneously and generating CUSUM data with a moving baseline over a set period in response to an observed value;   b) instructions for comparing said CUSUM data with a predetermined plurality of threshold values;   c) instructions for generating a signal when said CUSUM data exceeds any of said plurality of threshold values by a predetermined amount; and   d) instructions for generating a trimmed moving weighted mean and sigma such that observed data which previously resulted in the generation of a signal is excluded.   
     
     
         2 . The computer readable medium of  claim 1  wherein said instructions for measuring a plurality of CUSUMs simultaneously include instructions for measuring data from a group of time blocks measured from a current date wherein said group of time blocks consists of: seven days of data, fourteen days of data, twenty-one days of data and twenty-eight days of data measured from the current date. 
     
     
         3 . The computer readable medium of  claim 1  wherein the instructions for generating a trimmed moving weighted mean and sigma include instructions for excluding certain zero values. 
     
     
         4 . The computer readable medium of  claim 1  wherein said instructions for generating a signal include instructions for continuing to generate a signal until the observed value declines. 
     
     
         5 . A method for providing rapid syndrome analysis comprising:
 a) measuring a plurality of CUSUMs simultaneously and generating CUSUM data with a moving baseline over a set period in response to an observed value;   b) comparing said CUSUM data with a predetermined plurality of threshold values;   c) generating a signal when said CUSUM data exceeds any of said plurality of threshold values by a predetermined amount; and   d) generating a trimmed moving weighted mean and sigma such that observed data which previously resulted in the generation of a signal is excluded.   
     
     
         6 . The method of  claim 5  wherein the step of measuring a plurality of CUSUMs simultaneously includes the step of measuring data from a group of time blocks measured from a current date wherein said group of time blocks consists of: seven days of data, fourteen days of data, twenty-one days of data and twenty-eight days of data measured from the current data. 
     
     
         7 . The method of  claim 5  wherein the step of generating a trimmed moving weighted mean and sigma includes the step of excluding a variable percentage of extreme values and certain zero values.
