WebOLS induces a relative increase in bone turnover in favour of resorption, possibly due to malabsorption of vitamin D and/or calcium. However, no changes in bone mass or density are seen after 1 y of OLS treatment apart from those explained by the weight loss itself. Thus 1 y of OLS treatment seems safe from a 'bone preserving' point of view. Web09. maj 2024. · Abstract. Applied work often studies the effect of a binary variable (“treatment”) using linear models with additive effects. I study the interpretation of the OLS estimands in such models when treatment effects are heterogeneous. I show that the …

For example, multicollinearity between regressors may result in large variances and covariances for the OLS estimators, which could lead to unstable/poor parameter estimates. In practice, multicollinearity often pushes the parameter estimates ...
