Using numpy to perform some basic statistics.
Smacked into a major weirdness with the mean() function. I had an array of uint32s; the median() function returns 1370, and the mean returns 418746 ???
I read on Stack Overflow some confusion or problems using mean() with floats, but these are integers!
Some sanity checking:
#arr = np.ndarray((count,), dtype=np.uint32) len(arr): 10303 np.median(arr): 1370 np.mean(arr): 418746.462487 np.sum(arr): 19377507 np.sum(arr) / len(arr): 1880.76356401
Yup, I'm insane.
So you can get the correct value with
np.sum(arr) / len(arr)
np.mean(arr3, dtype="uint32", axis=0): 1880
As long as you don't care about the fractional part...
