Note.

The coefficients in the full model are interpreted as follows:

INF: Estimated mean of INF for the reference group (ESL)

AUX: Estimated mean of AUX for the reference group (ESL)

INF*GROUP: Estimated difference of INF for the TDL1 group compared to the ESL reference group; i.e., estimated mean for TDL1 is .1743 + .2700.

AUX*GROUP: Estimated difference of AUX for the TDL1 group compared to the ESL reference group; i.e., estimated mean for TDL1 is .5691 - 0.028.

The coefficients in the reduced model are interpreted as follows:

INF: Estimated mean of INF for the reference group (ESL)

AUX: Estimated mean of AUX for the reference group (ESL)

GROUP: Estimated difference for the TDL1 group compared to the ESL reference group for either variable; i.e., estimated mean for TDL1 group for INF is .2283 +.0897, and for AUX, the estimate is .5310 + .0897.
