Poverty and family adversity trajectories and Not in Education, Employment or Training (NEET) status in early adulthood: Evidence from the UK Millennium Cohort Study Open
Background Young people who are not in education, employment or training (NEET) are at an increased risk of long-term social and economic disadvantage. While previous research has linked various risk factors and individual characteristics …

Child poverty and under-5 children services spending on early childhood development in England – a longitudinal local area ecological study of children born between 2017 and 2022 Open
Summary Background School readiness has fallen in the UK recently. We investigated the contribution of changes in child poverty and early years spending to trends in children not developmentally on track at 2-2.5 years. Methods In this lon…

Unbiased estimation of the OLS covariance matrix when the errors are clustered Open
When data are clustered, common practice has become to do OLS and use an estimator of the covariance matrix of the OLS estimator that comes close to unbiasedness. In this paper, we derive an estimator that is unbiased when the random-effec…

A New Estimator for Standard Errors with Few Unbalanced Clusters Open
In linear regression analysis, the estimator of the variance of the estimator of the regression coefficients should take into account the clustered nature of the data, if present, since using the standard textbook formula will in that case…
