- Parameters:
- pafloat
Alternative proportion, forming the effect size with p0.
- p0float
Null proportion.
- alphafloat
Required significance.
- betafloat
Required beta (1 - power).
- alternative{‘two-sided’, ‘less’, ‘greater’}, optional
Sense of alternative hypothesis.
- method{‘norm-approx’, ‘arcsin’}, optional
- ‘norm-approx’Normal approximation to the binomial distribution. Solves
power_1sampleequal to requested power by changing nobs.‘arcsin’Inverse-sine approximation to the binomial distribution.
