Method Details

### __init__(self, alpha=1, beta=1) (Constructor) | source code
x.__init__(...) initializes x; see help(type(x)) for signature Overrides: object.__init__ (inherited documentation)

### log_prob(self, x) | source code
Evaluate the logarithm of the probability of observing values `x`. Parameters: `x` - values Returns: array Overrides: AbstractDensity.log_prob (inherited documentation)

### random(self, size=None) | source code
Generate random samples from the probability distribution. Parameters: `size` - number of values to sample Overrides: AbstractDensity.random (inherited documentation)

Property Details

### alpha Get Method: unreachable.alpha(self) Set Method: unreachable.alpha(self, value)

### beta Get Method: unreachable.beta(self) Set Method: unreachable.beta(self, value)
