Vector Autoregressions with Parsimoniously Time

... This paper studies vector autoregressive models with parsimoniously time-varying parameters. The parameters are assumed to follow parsimonious random walks, where parsimony stems from the assumption that increments to the parameters have a non-zero probability of being exactly equal to zero. We esti ...

Multiple Fixed Effects in Nonlinear Panel Data Models - Theory and Evidence

... However, econometric theory has mostly focused on single fixed effects. The present paper attempts to bridge part of this gap by looking at some specific nonlinear models. The empirical relevance is demonstrated using Monte Carlo simulations and an application to international trade data. This paper ...

Expectation–maximization algorithm



In statistics, an expectation–maximization (EM) algorithm is an iterative method for finding maximum likelihood or maximum a posteriori (MAP) estimates of parameters in statistical models, where the model depends on unobserved latent variables. The EM iteration alternates between performing an expectation (E) step, which creates a function for the expectation of the log-likelihood evaluated using the current estimate for the parameters, and a maximization (M) step, which computes parameters maximizing the expected log-likelihood found on the E step. These parameter-estimates are then used to determine the distribution of the latent variables in the next E step.
