Addressing housing deficits from a multi-dimensional perspective: a review of Chilean housing policyCortés Urra, V.A. (author), Czischke, D.K. (author), Gruis, V.H. (author)After decades of battling the quantitative and qualitative housing deficits, Latin American countries are seeing new types of challenges in housing. Neoliberal policies favouring individual (low-cost) homeownership have weakened social trust and solidarity between neighbours, and some housing areas face poor urban amenities. An example of this...journal article 2023

van Nee, Mirrelijn M. (author), Wessels, L.F.A. (author), van de Wiel, Mark A. (author)BACKGROUND: High-dimensional prediction considers data with more variables than samples. Generic research goals are to find the best predictor or to select variables. Results may be improved by exploiting prior information in the form of co-data, providing complementary data not on the samples, but on the variables. We consider adaptive ridge...journal article 2023
