Google Trends para previsão de variáveis macro: uso no Brasil através do algoritmo autometrics

open access: yes, 2017
This work aims to test if the use of Google Trends as an exogenous variable improves the prediction of the monthly data for Brazilian Formal Job Creation (CAGED) compared to a model that uses only the lags themselves.

Minimal prime ideals in autometrized algebras [PDF]

open access: yesCzechoslovak Mathematical Journal, 1994
An autometrized \(\ell\)-algebra is a lattice-ordered commutative monoid \(A\) with an additional binary operation on \(A\) satisfying the properties of a metric. The author shows some connections between prime ideals of \(A\) and prime filters on the positive cone \(A^ +\), and between prime ideals and polars of \(A\), where \(A\) belongs to a special

Model selection approaches of water quality index data [PDF]

open access: yes, 2016
Automatic model selection by using algorithm can avoid huge variability in model specification process compared to manual selection.With the employment of algorithm, the right model selected is then also used for forecasting purposes.

The Properties of Model Selection when Retaining Theory Variables [PDF]

open access: yes
Economic theories are often fitted directly to data to avoid possible model selection biases. We show that embedding a theory model that specifies the correct set of m relevant exogenous variables, x{t}, within the larger set of m+k candidate variables, (
