What is true about multiple linear regression and marginal linear models when dependence is present in data?

1 / 1 point

A multiple linear regression model is theoretically justified when there is dependence in the data.

Marginal linear model estimates and standard errors are meaningful due to the dependence of data, but only when dependence is strictly between observations within the same group.

The standard error in multiple linear regression tends to be higher than in marginal linear models.
