Howdy all! My first posting since comp.soft-sys.math.mathematica days!
I recently acquired a data-logging Geiger counter and have been fitting the time-series data (total counts per 1 minute interval). Since the numbers well exceed 1, the Poisson distribution I expect will look quite Gaussian. I bin the count rates then fit the data. The distributions are as expected EXCEPT that I keep finding in finer-scale histograms of the counts-per-minute data a much-larger-than-expected narrow peak right at the peak of the histogram.
(In graphic attached: red=Poisson, green=Gaussian.) Being a naive theoretical non-nuclear physicist, I'm puzzled. Can someone explain my data to me? :) Perhaps I am regressing to the normal (a pun, not an interpretation)?
Thanks! DMW
