GofChisquarePower.power(effect_size, nobs, alpha, n_bins, ddof=0)
[source]
Calculate the power of a chisquare test for one sample
Only twosided alternative is implemented
Parameters: 


Returns: 
power – Power of the test, e.g. 0.8, is one minus the probability of a type II error. Power is the probability that the test correctly rejects the Null Hypothesis if the Alternative Hypothesis is true. 
Return type:
