Verificación de calidad de modelos en regresión lineal software estadístico de regresión erla [PDF]
, 2011 En un análisis de Regresión Lineal, existen varios supuestos o premisas que deben ser considerados al momento de determinar la validez de un modelo, puesto que el no cumplimiento de alguno de estos supuestos podría conducirnos a modelos inestables, de ...

Copula‐based joint modelling of emergency department visits with time‐varying dependence
Canadian Journal of Statistics, EarlyView.Abstract Jointly modelling multiple correlated count time series is essential in health services research, where outcomes like emergency visits for mental health and substance use often evolve together. Ignoring these dependencies can obscure meaningful trends and limit the effectiveness of policy evaluation.

Canadian Journal of Statistics, EarlyView.Abstract This article presents a strategy for conducting regression analysis of zero‐truncated recurrent event data. The research is partly motivated by a pediatric mental health care (PMHC) program based on administrative data. We are particularly interested in how the occurrence of an event depends on its past occurrences and the associated ...

Lasso for hierarchical polynomial models
Canadian Journal of Statistics, EarlyView.Abstract The divisibility conditions implicit in a polynomial hierarchy suggest parameter constraints in regression. With this idea, we establish strong and weak hierarchies for both the lasso and relaxed lasso. Our proposal extends prior work on hierarchical lasso, which was mainly concerned with models of degree 2.

Drivers and Challenges of Micro‐Irrigation Adoption and Intensity in India: A Study of Four States
Irrigation and Drainage, EarlyView.ABSTRACT India's food security relies substantially on groundwater, but inefficient irrigation is seriously depleting this resource. Micro‐irrigation (MI) improves irrigation application efficiency and productivity, yet adoption remains low. This study examines MI adoption across four major Indian states—Uttar Pradesh, Maharashtra, Madhya Pradesh and ...
