Chapter 25 Appendix N: Calibration weighting control totals: interview sample

This table contains the statistical parameters of a logistic regression model used to model households that did not fully respond to the survey, that is where not every member of the household completed a seven-day travel diary. More details can be found in Chapter 5 - Weighting

Some shorthand is used in this table: [x] denotes no data present.
