## S4 method for signature 'Cpp_Clmbr'
cr( CL =0.95 , method ="CLR", incr, output ="G" )
``` |

`CL` |
confidence level, between 0 and 1. |

`method` |
"CLR" or "AF" which stand for conditional likelihood-ratio or approximate-F (rapid), see |

`incr` |
increment of theta values for the confidence region's boundary-points. |

`output` |
"G", "T" or "V" which stand for graph, text or value. |

This subroutine scans to determine the postulate values of (theta, alpha) that have significance level greater than 1-CL. It scans first along the (theta, alpha-MLE) ridge to determine the 'theta' boundary limits.

If 'output' is "G" or "T" then 'cr' graphs or prints-out the confidence region but does not return a value. If 'output' is "V" then 'cr' returns an N x 3 matrix of boundary points ( theta, min-alpha, max-alpha ).
