This study investigates the association between dedication commitment and sliding (moving through relationship transitions without considering the consequences) over 14 weeks for emerging adults in cyclical (partners who have broken up and renewed) and non-cyclical relationships. An autoregressive cross-lagged panel and bivariate latent growth curve analysis were conducted using three waves of ...

The aim of this paper is to provide simple nonparametric methods to estimate finitemixture models from data with repeated measurements. Three measurements suffice for the mixture to be fully identified and so our approach can be used even with very short panel data. We provide distribution theory for estimators of the mixing proportions and the mixture distributions, and various functionals the...

Most applications dealing with problems involving the face require a robust estimation of the facial salient points. Nevertheless, this estimation is not usually an automated preprocessing step in applications dealing with facial expression recognition. In this paper we present a simple method to detect facial salient points in the face. It is based on a prior Point Distribution Model and a rob...

We study and generalize the duplication model of Pastor-Satorras et al. [25]. This model generates a graph by iteratively “duplicating” a randomly chosen node as follows: We start at t0 with a fixed graph G(t0) of size t0. At each step t > t0 a new node vt is added. The node vt selects an existing node u from V (G(t − 1)) = {v1, ..., vt−1} uniformly at random (uar). The node vt then connects to...

We explore the semantic structure of how opinions on products and services are expressed in blogs and forums in the form of user needs. To optimize the efficiency of content delivery, we invert the product feature structure and propose a specific way to represent the user opinion content in forums and blogs, focusing on user needs about product qualities and features. The content is subject to ...

The classical distribution theory of the log likelihood ratio test statistic does not hold for testing homogeneity (i.e., no mixture) against mixture alternatives. Asymptotic theory for this problem is developed. For some special cases, asymptotically locally minimax tests are also found. It is pointed out that the main problem is lack of identifiability of the usual parameterization even when ...

Using a multivariate generalized autoregressive conditional heteroskedasticity (GARCH-M) model, we investigate volatility spillovers in six Southeast Asian stock markets around the time of the 1997 Asian crisis. We focus on interactions with the U.S. market as a world financial market, and with the Japanese market as a regional financial market. We also use bivariate GARCH-M models to examine t...

The exponential distribution is also the continuous analog of the geometric distribution in the following sense. In an experiment where the binomial distribution describes the number of successes in n trials, the geometric distribution describes the number of trials necessary for one success. In an experiment where the Poisson distribution describes the number of random occurrences of some even...
