Prediction

Prediction takes the information gleaned from one election and uses it to forecast the results of a new election. In this case, since the new election hasn't taken place, the systematic error component is inestimable, and the total error component is generated.

To enable predictive mode, add the option predict=TRUE to a judgeit analysis command. To specify new covariates for this election, add the option new.covariates to specify the new conditions, or use new.covariate.matrix to draw a new electoral map entirely.
