Coverage Probability of Bayesian method

1 | ```
covpBA(n, alp, a, b, t1, t2, a1, a2)
``` |

`n` |
- Number of trials |

`alp` |
- Alpha value (significance level required) |

`a` |
- Beta parameters for hypo "p" |

`b` |
- Beta parameters for hypo "p" |

`t1` |
- Lower tolerance limit to check the spread of coverage Probability |

`t2` |
- Upper tolerance limit to check the spread of coverage Probability |

`a1` |
- Beta Prior Parameters for Bayesian estimation |

`a2` |
- Beta Prior Parameters for Bayesian estimation |

Evaluation of Bayesian Highest Probability Density (HPD) and two tailed
intervals using coverage probability, root mean square statistic, and the proportion
of proportion lies within the desired level of coverage for the Beta - Binomial
conjugate prior model for the probability of success `p`

.
