Methods of model development

A psychographic segmentation model should be able to accurately predict the segment to which a consumer belongs with an acceptable level of confidence. Often there are trade-offs involved. For instance, a model may attain a higher level of predictability with a greater number of segments, but too many segments become unwieldy and infeasible to juggle when operationalizing the model. This also pertains to the number of questions used in the algorithm to classify consumers by segment. More questions may be more predictive, but there are diminishing returns past a certain number of questions, and too many questions decrease completion rates among consumers.
