`inver.calib`

uses the inverse frequentist approach to estimate an unknown X given observed vector y0 and calculates confidence interval estimates.

1 | ```
inver.calib(x, y, alpha, y0)
``` |

`x` |
numerical vector of regressor measurments |

`y` |
numerical vector of observation measurements |

`alpha` |
the confidence interval to be calculated |

`y0` |
vector of observed calibration value |
