Correction: Do family and neighbourhood matter in secondary school completion? A multilevel study of determinants and their interactions in a life-course perspective.

[This corrects the article DOI: 10.1371/journal.pone.0172281.].

There is an error in the first sentence of the Results section in the Abstract. The correct sentence is: Completion rates were significantly higher within families with higher education level (82% in tertiary educated families vs. 67% and 56% in secondary and primary educated families respectively) and were strongly correlated within families (ICC = 39.6) and neighbourhoods (ICC = 5.7).

There are multiple errors in Table 2. For the “Neighbourhood variance (95% CI)” and “Family variance (95% CI) levels”, the proportional change in variance (PCV) and median odds ratio (MOR) values in Model 6 are incorrectly omitted. For the “Neighbourhood variance (95% CI)”, “Family variance (95% CI)”, and “Family variance >1 child*” levels, the median odds ratio (MOR) values for Models 1–6 are incorrect. Please see the corrected Table 2 here.

* Family level variance from the secondary analysis containing only families with more than one child (S1 Table)

aThe proportional change in variance expresses the change in variance at the particular level from the empty model

There is an error in S1 Table. For the “Neighbourhood variance (95% CI)” and “Family variance (95% CI)” levels, the median odds ratio (MOR) values for Models 1–6 are incorrect. Please see the corrected S1 Table here.

There is an error in S3 Table. For the “Family variance (95% CI)” level, the median odds ratio (MOR) values for Models 1–6 are incorrect. Please see the corrected S3 Table here.
