Boletim 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 ...

Canadian 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

Hidden Markov graphical models with state‐dependent generalized hyperbolic distributions
Canadian Journal of Statistics, EarlyView.Abstract In this article, we develop a novel hidden Markov graphical model to investigate time‐varying interconnectedness between different financial markets. To identify conditional correlation structures under varying market conditions and accommodate shape features embedded in financial time series, we rely upon the generalized hyperbolic family of ...

Development and Testing of a Low‐Cost Soil Moisture Sensor for Real‐Time Irrigation Scheduling
Irrigation and Drainage, EarlyView.ABSTRACT Effective irrigation scheduling is essential for improved water management in irrigated areas, with soil moisture monitoring recognized as one of the most effective methods. However, challenges such as the high cost of sensors and the difficulties in monitoring large areas hinder their practical application, particularly for smallholder ...
