Continuity corrected Logit-Wald method of CI estimation

1 |

`x` |
- Number of successes |

`n` |
- Number of trials |

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

`c` |
- Continuity correction |

Wald-type interval for the logit transformation of the parameter `p`

using the test statistic
*(abs(L(phat)-L(p))-c)/SE*
where *c > 0* is a constant for continuity correction and *L(y) = log(y/1-y)*
for all *x = 0, 1, 2 ..n*. Boundary modifications when *x = 0* or *x = n*
using Exact method values.

`prop.test and binom.test`

for equivalent base Stats R functionality,
`binom.confint`

provides similar functionality for 11 methods,
`wald2ci`

which provides multiple functions for CI calculation ,
`binom.blaker.limits`

which calculates Blaker CI which is not covered here and
`propCI`

which provides similar functionality.
