Gerda Claeskens, Catholic University of Leuven, Belgium Lack-of-fit tests and order selection in inverse regression models.

We propose two test histogramme statistique for use in inverse regression problems where only noisy, indirect observations for the mean function histogramme statistique available.

Both test statistics have a counterpart in classical hypothesis testing, where histogramme statistique are called the order selection test and the data-driven Neyman smooth test. In a simulation study we show that the inverse order selection and Neyman smooth tests outperform their direct counterparts in many cases.

The methods are applied to data arising in confocal fluorescence microscopy. Here, images are observed with blurring modeled as deconvolution and stochastic histogramme statistique at subsequent times.

The aim is then to reduce the signal to noise ratio by averaging over the distinct images. In this context it is relevant to test whether the images are still equal or have changed by outside influences such as moving of the object table.

This is joint work with N. Standard exhaustive search methods for variable selection quickly become computationally infeasible, and forward selection methods are typically very unstable.

We will show histogramme statistique in generalized linear models, L1-penalty methods Lasso can be very powerful as a first step: Histogramme statistique, some adaptations correct Lasso's overestimation behavior, yielding consistent variable selection schemes, and their exhaustive computation can be done very efficiently.


Our illustrations cover both theory and methodology as histogramme statistique as concrete applications in molecular biology. Chris Skinner, University of South Hampton, UK Estimation of a Distribution Function from Survey Data with Nonresponse The estimation of a finite population distribution function from sample survey data is considered for the case when nonresponse is present.

It is assumed that information is available for all sample units on auxiliary variables which are predictive of the variable of interest.


Two broad approaches histogramme statistique considered: The paper histogramme statistique motivated by an application to the estimation of the distribution of hourly pay using data from the Labour Force Survey in the United Kingdom. In this case the main auxiliary variable is a proxy measure of the variable of interest.

Some theoretical and numerical comparisons of the approaches will be presented.


The latter are an interesting alternative to classifiers or posterior distributions of class labels. Their purpose is to quantify uncertainty when classifying a single observation, even if we histogramme statistique have information on the prior distribution of class labels.

After illustrating this concept with some examples and procedures, we focus on computational issues and discuss p-values involving regularization, in particular, LASSO type penalties, to cope with high-dimensional data.


Determining the Number of Factors In this talk we briefly present histogramme statistique general dynamic factor developed by Forni et al. Although developed in an econometric context, this method histogramme statistique likely to applyin all fields where a very large number of interrelated time series or signals are observed simultaneously.

We then consider the problem of identifying the number q of factors driving the panel. We show how the method can be implemented, and provide histogramme statistique and empirics illustrating its excellent finite histogramme statistique performance.

Application to real data brings some new contribution in the ongoing debate on the number of factors driving the US economy. The generalized dynamic factor model:
