# errBA: Calculates error, long term power and pass/fail criteria for...

### Description

Calculates error, long term power and pass/fail criteria for Bayesian method

### Usage

 `1` ```errBA(n, alp, phi, f, a, b) ```

### Arguments

 `n` - Number of trials `alp` - Alpha value (significance level required) `phi` - Null hypothesis value `f` - Failure criterion `a` - Beta parameters for hypo "p" `b` - Beta parameters for hypo "p"

### Details

Evaluation of Bayesian Highest Probability Density (HPD) and two tailed intervals using error due to the difference of achieved and nominal level of significance for the n + 1 intervals for the Beta - Binomial conjugate prior model for the probability of success `p`

### Value

A dataframe with

 `delalp` Delta-alpha is the increase of the nominal error with respect to real error `theta` Long term power of the test `Fail_Pass` Fail/pass based on the input f criterion `method` Name of method - Quantile or HPD
