Implementation commonly follows an easy random sample. In addition to permitting for stratification on an ancillary variable, poststratification may be used to implement weighting, that may Enhance the precision of the sample's estimates.
This undertaking wasn't an excellent in shape for standard Vitality modeling tools, so a custom spreadsheet was utilized to predict Electrical power use. Applying hourly weather conditions data heating Vitality was estimated (even though this was a supply of mistake as we were being much too optimistic in our assumptions for heating system effectiveness.
