pBeta¶
- pBeta(p1, p2, x, tail=False)¶
Cumulative distribution function of a Beta distribution on .
- Parameters:
- alphafloat,
Parameter .
- betafloat,
Parameter .
- xfloat
Location.
- tailbool, optional
Tail flag. Default value is False. If True, the complementary CDF is computed.
- Returns:
- pfloat
