kFactor¶
- kFactor(n, p, alpha)¶
Exact margin factor for bilateral covering interval of a Normal sample.
- Parameters:
- nint
The size of the sample.
- pfloat
The probability level of the covering interval.
- alphafloat
The confidence level of the covering interval.
- Returns:
- kfloat
The margin factor.
Notes
This method allows one to compute the exact margin factor of a Normal sample of size with unknown means and unknown common variance . It is equivalent to the pooled version with . This implements the standard NF ISO 16269-6.
Examples
>>> import openturns as ot >>> k = ot.DistFunc.kFactor(5, 0.95, 0.9)
