    62 It is possible to set the c.v. (or coefficient of variation calculated as the standard deviation of a time series' estimates relative to its mean) for time series as an optional second line in the csv time series file. Mark the second line in the file with "CV" in that case. From the CV we calculate the time series weight at the inverse, i.e. as the "signal to noise" ratio for the time series. The c.v. input have to be complete and positive values. Note that you can replace the calculation with your own, and enter "Weight" directly as the optional second line of the csv time series files.

The c.v. input have to be complete and positive values. Variability is assumed to be log-normal, in which case the CV is approximately equal to the standard deviation of the log prediction error. Weight is calculated from cv as equal to 1/CV^2. Note that you can replace the calculation with your own, and enter "Weight" directly as the optional second line of the csv time series files.
