Civiqs final Iowa Caucus poll performed well in a comparison with the major polls.
Root mean square error = RMSE
The root-mean-square deviation (RMSD) or root-mean-square error (RMSE) is a frequently used measure of the differences between values (sample or population values) predicted by a model or an estimator and the values observed.
In economics, the RMSD is used to determine whether an economic model fits economic indicators.
In experimental psychology, the RMSD is used to assess how well mathematical or computational models of behavior explain the empirically observed behavior.
