The sliced mean variance–covariance inverse regression (SMVCIR) algorithm takes grouped multivariate data as input and transforms it to a new coordinate system where the group mean, variance, and covariance differences are more apparent. Other popular algorithms used for performing graphical...

We present a new Stata estimation program, mboxcox, that computes the normalizing scaled power transformations for a set of variables. The multivari- ate Box–Cox method (defined in Velilla, 1993, Statistics and Probability Letters 17: 259–263; used in Weisberg, 2005, Applied Linear Regression...

We present a new Stata program, vselect, that helps users perform variable selection after performing a linear regression. Options for stepwise meth- ods such as forward selection and backward elimination are provided. The user may specify Mallows’s Cp, Akaike’s information criterion,...

We present a new Stata command, mmp, that generates marginal model plots (Cook and Weisberg, 1997, Journal of the American Statistical Association 92: 490–499) for a regression model. These plots allow for the comparison of the fitted model with a nonparametric or semiparametric model fit. The...

Abstract The issue of climate change and its potential effects on natural and human systems is becoming more prevalent on citizen and policymaker agendas. Studies of the factors framing citizen levels of concern about climate change and potential policy reactions to it are mainly framed around...

Following spatial choice theory and MAP methodology, we employ the data drawn from recent nationwide public opinion surveys to probe the latent political choice space in American political competition. Our analyses demonstrate that, in addition to the traditional left–right ideology...

The relatively low level of concern about climate change among Americans has important implications for climate policy. While many studies have examined individual characteristics associated with climate change attitudes, fewer studies have considered the effects of environmental conditions on...

This study reviews and synthesizes the literature on foreign direct investment in the Philippines in terms of the size, composition, determinants and the benefits and costs of direct investment in the Philippines. The study shows that while the benefits from foreign investments are not...

Three experiments examine how prevention-focused and promotion-focused consumers evaluate the comparison brand and what information they anchor on in direct comparative ads framed positively or negatively. Negative (vs. positive) frames lead prevention-focused respondents to exhibit higher...
