STATISTICAL MODELING OF LONGITUDINAL DATA IN VETERINARY AND MEDICAL SCIENCES

J Chaudhary
2015 International Journal of Livestock Research  
In longitudinal studies we take repeated measurements of the same individual over a time span to encompass a detectable change in their disease/developmental status.  ...  A key strength of a longitudinal study is the ability to measure change in outcomes and/or exposure at the individual/animal level.  ...  Finally, if we allow the coefficients of the explanatory variables vary from subject to subject, we have mixed effect models, in contrast with the models containing same coefficients of the explanatory  ...

Semiparametric Bayesian inference in smooth coefficient models

Gary Koop, Justin L. Tobias
2006 Journal of Econometrics  
We describe procedures for Bayesian estimation and testing in both cross sectional and longitudinal data smooth coefficient models (with and without endogeneity problems).  ...  The smooth coefficient model is a generalization of the partially linear or additive model wherein coefficients on linear explanatory variables are treated as unknown functions of an observable covariate  ...  We then develop a generalized set of tools for estimating smooth coefficient models in a hierarchical (longitudinal) context, and finally, in a longitudinal data context with an endogeneity problem.  ...

1998 The Journal of human resources  
Sloan Foundation and the Centerfor Advanced Study in the Behavioral Sciences is gratefully acknowledged.  ...  Because y does not vary with the regressors x when it is censored (unlike the true variable y*), standard least squares regression will underestimate the magnitude of the regression slope coefficients.  ...  For each pair of years, the absolute error loss function was used to estimate the identically censored panel data model with fixed effects.  ...
