Abstract

A method and apparatus for generating a statistic based upon a persistence data is provided. The method comprises the steps of defining a plurality of slices of data comprising a persistence data and generating a histogram of the data within each of the plurality of slices. A parameter is measured for each of the generated histograms, and the measured parameters are plotted corresponding to each of the generated histograms.

Claims

1. A method for generating a statistic based upon persistence data, comprising the steps of:

defining a plurality of slices of data comprising a persistence data;

generating a histogram of the data within each of the plurality of slices;

calculating a parametric measurement for each of the generated histograms; and

plotting the calculated parametric measurement corresponding to each of the generated histograms.

2. The method of claim 1, wherein the calculated parametric measurements are plotted against a time axis in an order corresponding to the relative positioning of the corresponding data slices.

3. The method of claim 1, wherein at least two of the plurality of slices are contiguous in time.

4. The method of claim 1, wherein the parameter is one of the following:

(i) standard deviation, (ii) minimum measurements, (iii) maximum measurements, (iv) number of peaks, (v) amplitude, (vi) peak-to-peak, (vii) mean, (viii) top, (ix) base, (x) x at peak, (xi) full width at population, (xii) maximum population, (xiii) median, (xiv) mode, (xv) percentile, (xvi) range, (xvii) root mean square, or (xviii) total population.

5. A method for defining a parameter for a portion of a persistence data, comprising the steps of:

defining a slice comprising persistence data corresponding to a predefined time interval;

generating a histogram of the data within the slice; and

calculating a parametric measurement for the generated histogram.

6. The method of claim 5, wherein the predefined time interval corresponds to a time interval relative to a start of the persistence data.

7. The method of claim 5, wherein the predefined time interval corresponds to a time interval on a display.

8. A computer program for generating a statistic based upon a persistence data, the computer program comprising instructions for:

defining a plurality of slices of data comprising a persistence data;

generating a histogram of the data within each of the plurality of slices;

calculating a parametric measurement for each of the generated histograms; and

plotting the calculated parametric measurements corresponding to each of the generated histograms.

9. The computer program of claim 8, wherein the calculated parametric measurements are plotted against a time axis in an order corresponding to the relative positioning of the corresponding data slices.
