scaleandperiods {BNPTSclust} | R Documentation |

This function scales the time series data in the interval [0,1] as deemed necessary in Nieto-Barajas and Contreras-Cristan (2014) for the time series clustering algorithm. It also obtains the time periods of the data set provided.

scaleandperiods(data,scale)

`data` |
Data frame with the time series information. |

`scale` |
Flag that indicates if the time series data should be scaled to the [0,1] interval with a linear transformation as proposed by Nieto-Barajas and Contreras-Cristan (2014). If TRUE, then the time series are scaled to the [0,1] interval. Its value comes directly from the "scale" argument of the clustering functions. |

The function considers that the time periods of the data appear as row names.

`periods` |
array with the time periods of the data. |

`mydata` |
data frame with the time series data scaled in [0,1]. |

`cts` |
variable that indicates if some time series were removed because they were constant in time. If no time series were removed, cts = 0. If there were time series removed, cts indicates the column of such time series. |

For internal use.
