Abstract: A pair of polychotomous random variables $$(Y_1,Y_2)^\top =:{\varvec{Y}}$$(Y1,Y2)⊤=:Y, where each $$Y_j$$Yj has a totally ordered support, is studied within a penalized generalized linear model framework. We deal with a triangular generating process for $${\varvec{Y}}$$Y, a… read more here.

DOI: 10.3389/fpsyg.2022.979341
Abstract: Konrad Lorenz, an ethologist, proposed that certain physical elements are perceived as cute and induce caretaking behavior in other individuals, with the evolutionary function of enhancing offspring survival. He called these features Kindchenschema, baby schema.… read more here.
