The

The team's novel approach — featuring the first demonstration of a frequency tritter, an instrument that splits light into three frequencies — returned experimental

predictions and showed that many quantum information processing operations can be run simultaneously without increasing
error.

If the
predictions by the model do not agree with the measured data we know exactly which aspect of the modeling is in
error and we can adjust that single parameter with assurance that we can obtain the correct
results solely by the actions of this single parameter.
If you would like your modeling
result to be taken seriously as a guide to future planning (I don't mean to presume to know your motives), then keep track of the squared
prediction error, the sum of the squared
prediction errors (CUSUM), and the square root of the mean
prediction error (RMSE) over the next 20 years.
If the PLS method were able to minimize cross-validation based
prediction error when forming each PLS component, rather than maximizing cross-covariance, then it probably would achieve a superior
result (lower Spread ratio) when using all predictors simultaneously than just any one of them, but such a method would be extremely computationally demanding.
Anyone predicting temperatures say 10 years ahead with influence on policy should be required to deposit $ 100,000 of their own money to be forfeited if the actual
