About job market outcomes: Assessing the performance of Colombian higher education institutions by Saavedra‐Caballero, Fabiola, Van Bellegem, Sébastien

“…One method for evaluating higher education performance is to conceptualize it as a production function represented as an input/output process. This paper…”

Instrumental variable estimation in functional linear models by Florens, Jean-Pierre, Van Bellegem, Sébastien

“…In an increasing number of empirical studies, the dimensionality measured e.g. as the size of the parameter space of interest, can be very large. Two instances…”

Locally Adaptive Estimation of Evolutionary Wavelet Spectra by Van Bellegem, Sébastien, von Sachs, Rainer

“…We introduce a wavelet-based model of local stationarity. This model enlarges the class of locally stationary wavelet processes and contains processes whose…”

School System Evaluation by Value Added Analysis Under Endogeneity by Manzi, Jorge, San Martín, Ernesto, Van Bellegem, Sébastien

“…Value added is a common tool in educational research on effectiveness. It is often modeled as a (prediction of a) random effect in a specific hierarchical…”

Instrumental regression in partially linear models by Florens, Jean-Pierre, Johannes, Jan, Van Bellegem, Sébastien

“…We consider the semi-parametric regression model Y = X t β + Φ(Z) where β and Φ(·) are unknown slope coefficient vector and function, and where the variables…”

Increasing emotional intelligence to decrease healthcare expenditures: How profitable would it be? by Mikolajczak, Moïra, Van Bellegem, Sébastien

“…While numerous studies document the impact of emotional intelligence on health, no study has estimated the associated economic impact. As a result, the return…”

Semiparametric estimation by model selection for locally stationary processes by Van Bellegem, Sébastien, Dahlhaus, Rainer

“…Over recent decades increasingly more attention has been paid to the problem of how to fit a parametric model of time series with time-varying parameters. A…”

Nonparametric simultaneous testing for structural breaks by Gao, Jiti, Gijbels, Irène, Van Bellegem, Sébastien

“…In this paper we consider a regression model with errors that are martingale differences. This modeling includes the regression of both independent and time…”

Log-density Deconvolution by Wavelet Thresholding by BIGOT, JÉRÉMIE, BELLEGEM, SÉBASTIEN VAN

“…This paper proposes a new wavelet-based method for deconvolving a density. The estimator combines the ideas of non-linear wavelet thresholding with periodized…”

Forecasting non-stationary time series by wavelet process modelling by FRYZLEWICZ, Piotr, VAN BELLEGEM, Sébastien, VON SACHS, Rainer

“…Many time series in the applied sciences display a time-varying second order structure. In this article, we address the problem of how to forecast these…”

Forecasting economic time series with unconditional time-varying variance by Van Bellegem, Sébastien, von Sachs, Rainer

“…The classical forecasting theory of stationary time series exploits the second-order structure (variance, autocovariance, and spectral density) of an observed…”

Evolutionary Coherence of Nonstationary Signals by Ombao, H., Van Bellegem, S.

“…Coherence is a widely used measure for characterizing linear dependence between a pair of signals. For nonstationary signals, the autospectrum, cross spectrum,…”
