Sensitivity of results to predictors or
predictands used and to the number of PLS components used.
Not exact matches
This is PCR, although PCs are
used as predictors; but not as
predictands.
Statistical downscaling is based on relationships linking large - scale atmospheric variables from either GCMs or RCMs (predictors) and local / regional climate variables (
predictands)
using observations.
In either case, the prediction error reduces to zero when the maximum number of PLS components is
used (one less than the number of models), since then there are sufficient degrees of freedom available to exactly fit each CMIP5 model's
predictand.
The left hand panels all involve RCP8.5 2090 ΔT as the
predictand, but with the nine different predictors
used separately.
The right hand panels involve different
predictands, with all predictors
used simultaneously.
b, As in a but
using all nine of the predictor fields simultaneously while switching the
predictand that is targeted.
Using Visible and Built - Up as the
predictand variables we can increase the correlation to 0.8.
The average RASST values within these partition elements are
used as predictors in a multiple linear regression, with the global mean temperature as the
predictand.
