Partially linear single-index models for longitudinal data

In this article, we study a partially linear single-index model for longitudinal data under a general framework which includes both the sparse and dense longitudinal data cases. The proposed method can naturally be applied to deal with pure single-index models and partially linear models for longitudinal data. Some simulation studies are carried out and an example in In this article, we study a partially linear single-index model for longitudinal data under a general framework which includes both the sparse and dense longitudinal data cases.

We fit the data with PLSiM by using the standardized continuous variables as the single index components, including X 1 = LEV ERAGE, X 2 = ASSETMAT, X 3 = MV / BV, X 4 = SIZE, X 5 = CHNGEEPS, X 6 = GTAXRATE, X 7 = BTAXRATE, X 8 = V AR, and X 9 = TER M. In addition, the two dummy variables, LOWBOND and HIGHBOND, are the linear components, i.e., Z 1 = LOWBOND and Z 2 = HIGHBOND. Downloadable! In this article, we study a partially linear single-index model for longitudinal data under a general framework which includes both the sparse and dense longitudinal data cases. A semiparametric estimation method based on the combination of the local linear smoothing and generalized estimation equations (GEE) is introduced to estimate the two parameter vectors as well as the We consider marginal generalized partially linear single-index models for longitudinal data. A profile generalized estimating equations (GEE)-based approac Within a wide range of bandwidths for estimating the nonparametric function, our profile GEE estimator is consistent and asymptotically normal even if the covariance structure is misspecified. In this article, a partially linear single-index model for longitudinal data is investigated. The generalized penalized spline least squares estimates of the unknown parameters are suggested. All parameters can be estimated simultaneously by the proposed method while the feature of longitudinal data is considered.

Abstract. In this paper, we consider the partially linear single-index models with longitudinal data. To deal with the variable selection problem in this context, we propose a penalized procedure combined with two bias correction methods, resulting in the bias-corrected generalized estimating equation and the bias-corrected quadratic inference function, which can take into account the

In contrast, as mentioned in Section 1, our framework For partially linear single-index models, it is interesting to test whether the single-index part can be replaced by a linear expression of the index function. That means we are interested in testing (3.1) H 0 : g ( t ) = α 0 + α 1 t ↔ H 1 : g ( t ) ≠ α 0 + α 1 t , where α 0 and α 1 are two unknown parameters.
