data BetaDistribution Source #
The beta distribution
Instances
Constructor
:: Double | Shape parameter alpha |
-> Double | Shape parameter beta |
-> BetaDistribution |
Create beta distribution. Both shape parameters must be positive.
:: Double | Shape parameter alpha |
-> Double | Shape parameter beta |
-> Maybe BetaDistribution |
Create beta distribution. Both shape parameters must be positive.
:: Double | Shape parameter alpha |
-> Double | Shape parameter beta |
-> BetaDistribution |
Create beta distribution. Both shape parameters must be non-negative. So it allows to construct improper beta distribution which could be used as improper prior.
:: Double | Shape parameter alpha |
-> Double | Shape parameter beta |
-> Maybe BetaDistribution |
Create beta distribution. Both shape parameters must be non-negative. So it allows to construct improper beta distribution which could be used as improper prior.
