| x | finite real nonempty vector or matrix with values in the open interval (0, 1): sample data. |
| alpha | scalar in the range [0, 1]: significance level. Default is 0.05. |
| Parameter | Description |
|---|---|
| phat | array: beta distribution shape parameter estimates. |
| pci | array: confidence intervals for the estimates. |
betafit estimates the two shape parameters of the beta distribution.
