Oral Presentation
We propose a new multiple imputation technique for imputing squares. Cur-
rent methods yield either unbiased regression estimates, or preserve data re-
lations. No method, however, seems to deliver both, which limits researchers
in the implementation of regression analysis in the presence of missing data.
Besides, current methods only work under a MCAR mechanism. Our method
for imputing squares uses a polynomial combination. The proposed method
yields both unbiased regression estimates, whilst at the same time preserving
the quadratic relations in the data for both MAR and MCAR mechanisms.
