Synthetic data set to exemplify the use of the functions contained in NonParRolCor
Description
The data set syntheticdata contains three columns: the first one are the “times” (from 1 to 500) (named “Times”), the second (named “X”) and the third (named “Y”) columns were generated by a bi-variate AR1 process with similar autocorrelation coefficients of 0.25. We generate two correlated bi-variate AR1 time series with positive (direct) correlation (0.85) for the first 250 elements and with negative (inverse) correlation (-0.85) for the last 250 elements (Polanco-Martínez and López-Martínez 2021).
Usage

Format
