These functions are modified version of `trafo::trafos`

written by Lily Medina, Piedad Castro, Ann-Kristin Kreutzmann, Natalia Rojas-Perilla `trafo`

package.
Please review manual and vignette documents of latest `trafo`

package. The `ATA.Transform`

function works with many different types of inputs.

ATA.Transform(
X,
tMethod = c("BoxCox", "BoxCox Shift", "Sqrt", "Sqrt Shift", "Reciprocal", "Log",
"Log Shift", "NegLog", "Modulus", "Bickel-Doksum", "Manly", "Dual", "Yeo-Johnson",
"GPower", "GLog"),
tLambda,
tShift = 0,
bcMethod = c("loglik", "guerrero"),
bcLower = 0,
bcUpper = 1
)
``` |

`X` |
a numeric vector or time series of class |

`tMethod` |
Box-Cox power transformation family is consist of "BoxCox", "BoxCox Shift", "Sqrt", "Sqrt Shift", "Reciprocal", "Log", "Log Shift", "NegLog", "Modulus", "Bickel-Doksum", "Manly", "Dual", "Yeo-Johnson", "GPower", "GLog" in ATAforecasting package. |

`tLambda` |
Box-Cox power transformation family parameter. If NULL, data transformed before model is estimated. |

`tShift` |
Box-Cox power transformation family shifting parameter. If NULL, data transformed before model is estimated. |

`bcMethod` |
Choose method to be used in calculating lambda. "loglik" is default. Other method is "guerrero" (Guerrero, V.M. (1993)). |

`bcLower` |
Lower limit for possible lambda values. The lower value is limited by -5. Default value is 0. |

`bcUpper` |
Upper limit for possible lambda values. The upper value is limited by 5. Default value is 1. |

A list object consists of transformation parameters and transformed data.
`ATA.Transform`

is a list containing at least the following elements:

trfmX : Transformed data

tLambda : Box-Cox power transformation family parameter

tShift : Box-Cox power transformation family shifting parameter
