WebJul 24, 2024 · Here the null hypothesis is: the discreet random variable is not significantly different from the expected distribution. Unlike chi2_contingency, chisquare returns chi-square statistic and the p-value. To look at the expected distribution (by the algorithm) call ‘expected_freq’ from ‘scipy.stats’ and pass the observed value table in it. WebArguments bins. A list of data frames.

However: print (min (x for x in range (1,300) if x % 2 != 0 if x % 2 != 1)) Output: ValueError: min () arg is an empty sequence. There are no integers that are both odd and even, so there are no values for min to see, so it throws an exception. I deduce that in your code, there are no values that pass both conditions.
