Rebaixamento do capim-marandu para o diferimento e seus efeitos sobre índice de área foliar e número de meristemas apicais

open access: yesBoletim de Indústria Animal, 2016
Objetivou-se compreender como a estratégia de desfolhação prévia ao período de diferimento modifica a estrutura da Brachiaria brizantha cv. Marandu (capim-marandu) no início do diferimento. Três estratégias de desfolhação avaliadas foram 15/15 cm: dossel com 15 cm nos três meses antecedentes ao diferimento; 30/15 cm: dossel com 30 cm nos três meses ...

On subset least squares estimation and prediction in vector autoregressive models with exogenous variables

open access: yesCanadian Journal of Statistics, EarlyView.
Abstract We establish the consistency and the asymptotic distribution of the least squares estimators of the coefficients of a subset vector autoregressive process with exogenous variables (VARX). Using a martingale central limit theorem, we derive the asymptotic normal distribution of the estimators. Diagnostic checking is discussed using kernel‐based
