In macroeconomic forecasting, principal component analysis (PCA) has been the most prevalent approach to the recovery of factors, which summarize information in a large set of macro predictors. Nevert...
High dimensional stochastic regression with latent factors, endogeneity and nonlinearity
α-mixing, dimension reduction instrument variables nonstationarity time series
2016/1/20
We consider a multivariate time series model which represents a high dimensional vector process as a sum of three terms: a linear regression of some observed regressors,a linear combination of some la...
Sensitivity Analysis to Select the Most Influential Risk Factors in a Logistic Regression Model
Risk Factors Logistic Regression Model

The traditional variable selection methods for survival data depend on iteration procedures, and control of this process assumes tuning parameters that are problematic and time consuming, especially i...

We study isomorphism invariant point processes of R^d; whose groups of symmetries are almost surely trivial. We define a 1-ended, locally finite tree factor on the points of the process, that is, a ma...
Let X and Y be Poisson point processes on the real numbers with rates l_1 and l_2 respectively. We show that if l_1 > l_2, then there exists a deterministic map f such that f(X) and Y have the same di...
Scaling factors for ab initio vibrational frequencies：comparison of uncertainty models for quantified prediction
Bayesian data analysis Model calibration Scaling factor Vibrational frequency
2010/3/17
Bayesian Model Calibration is used to revisit the problem of scaling factor calibration for
semi-empirical correction of ab initio calculations. A particular attention is devoted to
uncertainty eval...
Statistical testing procedure for the interaction effects of several controllable factors in two-valued input-output systems
Confoundings Contingency tables Controllable factors Covariate matrix Generalized linear models Hierarchical models
2010/4/29
Suppose several two-valued input-output systems are designed by setting the
levels of several controllable factors. For this situation, Taguchi method has proposed
to assign the controllable factors...

How predictable is the academic success of individual undergraduate students at an
AACSB-accredited business school? As a group, undergraduate business students pose many
different intelligence leve...
