High-dimensional and time-dependent data pose significant challenges to Statistical Process Monitoring (SPM). Most of the high-dimensional methodologies to cope with these challenges rely on some form of Principal Component Analysis (PCA) model, usually classified as non-adaptive and adaptive. Non-adaptive methods include the static PCA approach an...
Article
Full-text available
Methods based on principal component analysis (PCA) are widely used for statistical process monitoring of high-dimensional processes. Allowing the monitoring model to update as new observations are acquired extends this class of approaches to non-stationary processes. The updating procedure is governed by a weighting parameter that defines the rate...

Full-text available
When a child does not seem to be ready for primary school, a popular practice is to grant the child more time by letting it repeat kindergarten. However, previous quasi-experimental research demonstrated negative, though diminishing, effects of kindergarten retention on academic learning during the first years of primary school. The present study e...
Article
The Projection Congruent Subset (PCS) Outlyingness is a new index of multivariate outlyingness obtained by considering univariate projections of the data. Like many other outlier detection procedures, PCS searches for a subset which minimizes a criterion. The difference is that the new criterion was designed to be insensitive to the outliers. PCS i...
