- Parameters:
- pafloat
Alternative hypothesis proportion, forming effect size.
- H0_propfloat
Null-hypothesis proportion.
- nobsint
Number of observations.
- alphafloat
Required significance.
- alternative{‘two-sided’, ‘less’, ‘greater’}, optional
Sense of alternative hypothesis.
- method{‘norm-approx’}, optional
Test method. Only ‘norm-approx’, the normal approximation to the binomial distribution is implemented.
