When using the intention-to-treat method to deal with non-compliance:
A) The higher the compliance rate, the more likely the ITT estimate overstates the true coefficient.
B) The higher the compliance rate, the further away (lower) the coefficient estimate is from the true coefficient.
C) The lower the compliance rate, the closer the coefficient estimate is to the true coefficient.
D) The lower the compliance rate, the further away (lower) the coefficient estimate is from to the true coefficient.

The lower the compliance rate, the more likely there will be a bias towards the null hypothesis, meaning that the ITT estimate will be lower than the true coefficient. This is because non-compliers tend to be systematically different from compliers, and excluding them from the analysis can lead to an underestimation of the treatment effect. Therefore, the lower the compliance rate, the further away (lower) the coefficient estimate is from the true coefficient.
