Semiparametric transition models [PDF]
A new semiparametric time series model is introduced – the semiparametric transition (SETR) model – that generalizes the threshold and smooth transition models by letting the transition function to be of an unknown form. Estimation is based on a combination of the (local) least squares estimations of the transition function and regression parameters ...

Model and Variable Selection Procedures for Semiparametric Time Series Regression
Semiparametric regression models are very useful for time series analysis. They facilitate the detection of features resulting from external interventions.

Semiparametric Regression in Capture–Recapture Modeling [PDF]
SummaryCapture–recapture models were developed to estimate survival using data arising from marking and monitoring wild animals over time. Variation in survival may be explained by incorporating relevant covariates. We propose nonparametric and semiparametric regression methods for estimating survival in capture–recapture models.

A Semiparametric Sequential Ordinal Model with Applications to Analyse First Birth Intervals
A semiparametric sequential ordinal model is proposed to analyze socio-demographic and spatial determinants of first birth intervals after marriage. Random effects are introduced to capture spatially structured and unstructured latent covariates.

Semiparametric Integrated and Additive Spatio-Temporal Single-Index Models
In this paper, we introduce two semiparametric single-index models for spatially and temporally correlated data. Our first model has spatially and temporally correlated random effects that are additive to the nonparametric function, which we refer to as ...

NONPARAMETRIC ESTIMATION OF SEMIPARAMETRIC TRANSFORMATION MODELS [PDF]
In this paper we develop a nonparametric estimation technique for semiparametric transformation models of the form:H(Y) =φ(Z) +X′β+UwhereH,φare unknown functions,βis an unknown finite-dimensional parameter vector and the variables (Y,Z) are endogenous.

A semiparametric model for cluster data
In the analysis of cluster data, the regression coefficients are frequently assumed to be the same across all clusters. This hampers the ability to study the varying impacts of factors on each cluster. In this paper, a semiparametric model is introduced to account for varying impacts of factors over clusters by using cluster-level covariates.
