Following publication of the original article [1], the authors reported an error in equation and in text.

Equation must be as follows:

$$y_{i} = \beta_{0} + \boldsymbol{x}_{i}\boldsymbol{\beta}_{\boldsymbol{1}} + \left(\beta_{t} + \boldsymbol{x}_{i}\boldsymbol{\beta}_{\boldsymbol{2}} \right)\mathbb{1}(t_{i}=1) + \epsilon_{i},$$

The following text must be: Correct specification of the S = 2 covariate distribution.

The original article has been updated.
