Previsão e interação dos preços da celulose brasileira nos mercados interno e externo

Abstract: A produção e a exportação de celulose são componentes importantes da economia no país. O objetivo desta pesquisa foi prognosticar o preço nos mercados interno e externo da celulose brasileira e avaliar a interferência entre o preço médio da celulose vendida em atacado e o preço médio da celulose exportada pelo Brasil. O estudo utilizou dados oriundos do Informativo Florestal do Centro de Estudos Avançados em Economia Aplicada (CEPEA), coletados entre junho de 2008 a março de 2018. Os modelos Autorregressivos I… Show more

“…To understand behavior and series generator process, Autoregressive Integrated Moving Average models (ARIMA) were applied to capture serial correlation effects, as long as the series were stationary (Morettin, 2016). The autocorrelation function (ACF) and the partial autocorrelation function (PACF) were applied to determine which ARIMA filter will be used: AR, MA, ARMA, ARIMA or SARIMA (Souza, 2016;Reichert & Souza, 2020).…”
