"Feedback in international migration: Brazilian and Ukrainian migration to Portugal" abstract After the remarkable migration inflows that occurred during the late 1990s and early 2000s, Brazilians and Ukrainians became the two largest foreign nationalities present in Portugal. Since then, there has been a stabilisation and a recent decline of the flow. While the economic crisis…

"A Test for Instrument Validity" Abstract This paper develops a specification test for instrument validity in the heterogeneous treatment effect model with a binary treatment and a discrete instrument. The strongest testable implication for instrument validity is given by the condition for non-negativity of point- identifiable complier’s outcome densities. Our specification test infers this testable…

Seminars in Statistics Piotr Zwiernik (University of Genova)

Maximum likelihood estimation for linear Gaussian covariance Models We study parameter estimation in linear Gaussian covariance models, which are p-dimensional Gaussian models with linear constraints on the covariance matrix. Maximum likelihood estimation for this class of models leads to a non-convex optimization problem which typically has many local optima. We prove that the log-likelihood function…

Seminars in Statistics Luigi Malagò (Shinshu University, Japan)

Information geometry of the Gaussian distribution in view of stochastic optimization: first and second order geometry We study the optimization of a continuous function by its stochastic relaxation, i.e., the optimization of the expected value of the function itself with respect to a density in a statistical model. In the first part of the talk…
