can then look at the accuracy of these predictions to see whether chosen groups are effective ones |

how DFA works
|
MANOVA performed (max. discrimination between DVs) and then ask how far each data point is from group centroids (like cluster analysis)
|
|
|
DFA good predictor?
|
assess sig. using MANOVA methods
calculate proportion successfully predicted (compared to chance-level) discrimination function coefficients |
|
|
discrimination function coefficients
|
show relative contribution of each DV (impact each one has)
standardise to allow for comparison |
