Different multivariate regression type of estimators for finite population variance under multiphase sampling set up in presence of two auxiliary variables have been suggested. These estimators are compared with estimators using no auxiliary variable or single auxiliary variable theoretically and with the help of numerical examples. 2000 Mathematics Subject Classification: 62D05.
