rsquare {phenex} | R Documentation |
Calculates the squared Pearson correlation coefficient of corrected and modelled timeserie.
rsquare(x)
x |
An object of class ‘NDVI’ containing corrected and modelled values. If corrected timeserie is not available, the raw one out of ‘values’ will be used |
The squared Pearson correlation coefficient as numeric value.
