Partial Least Squares (PLS) refer to a class of dimension-reduction techniques aiming at the identification two sets components with maximal covariance, model relationship between observed variables $x\in\mathbb{R}^p$ and $y\in\mathbb{R}^q$, $p\geq 1, q\geq 1$. Probabilistic formulations have recently been proposed for several versions PLS. Focusing first on probabilistic formulation PLS-SVD by...

Regression models with compositional response have been studied from the beginning of the log-ratio approach for analysing compositional data. These early approaches suggested the statistical hypothesis of logistic-normality of the compositional residuals to test the model and its coefficients. Also, the Dirichlet distribution has been proposed as an alternative model for compositional residual...

We study the problem of implementing social choice correspondences using the concept of undominated Nash equilibrium, i.e. Nash equilibrium in which no one uses a weakly dominated strategy. We show that this mild refinement of Nash equilibrium has a dramatic impact on the set of implementable correspondences. Our main result is that if there are at least three agents in the society, then any co...

Several issues concerning stepped care are discussed: the constraints of using Diagnostic and Statistical Manual of Mental Disorders diagnoses in randomized clinical trials (RCTs), the importance of basic and process research, the unintended negative effects of exaggerated claims of effectiveness and efficiency, the limits of RCTs in evaluating improvement and deterioration, the self-correcting...

A central characteristic ofpeople with PraderWilli Syndrome (PWS) is an apparent insatiable appetite leading to severe overeating and the potentialfor marked obesity and associated serious health problems and premature death. This behaviour may be due to the effects of the genetic defect resultingfrom the chromosome 15 abnormalities associated with the syndrome. We examine the ethical and legal...

Nonlinear structural equation modeling provides many advantages over analyses based on manifest variables only. Several approaches for the analysis of latent interaction effects have been developed within the last 15 years, including the partial least squares product indicator approach (PLS-PI), the constrained product indicator approach using the LISREL software (LISREL-PI), and the distributi...

Most industrialized countries have increased access to abortion over the past 30 years. Economic theory predicts that abortion laws affect sexual behavior since they change the marginal cost of having risky sex. We use gonorrhea incidence as a metric of risky sexual behavior. Using a panel of 41 North American, European and Central Asian countries over the period 1980-2000, we estimate the impa...

Structural equation modelling (SEM) is now a popular technique in the social, behavioural and business sciences for exploring and assessing complex linear relationships among many variables, in particular between endogenous and exogenous latent variables that cannot be directly observed but that must be inferred by means of manifest indicator variables, that is variables measured without error....

The mitotic cell-cycle mutation cdc4 has been reported to block the initiation of nuclear DNA replication and the separation of spindle plaques after their replication. Meiosis in cdc4/cdc4 diploids is normal at the permissive temperature (25 degrees) and is arrested at the first division (one-nucleus stage) at the restrictive temperature (34 degrees or 36 degrees). Arrested cells at 34 degrees...
