“…However, the possibilities of overinclusion and the selection of an entirely spurious 'best subset' were investigated. If, for instance, too many variables were included, some of which did not contribute to separation, or if none of the included expectancies were actually good discriminators despite apparently acceptable levels of statistical significance, then the solution would not likely be stable, i.e., a different 'best subset' would emerge if the study were repeated (Rencher and Larson 1980). The stability of the solution shown in table 1 was hence investigated by the following cross-validation procedures.…”

The relation between type or form of alcoholic beverage consumed and expectations about emotional or behavioral concomitants of drinking was investigated. One hundred and thrty-four Finnish undergraduates (45 men and 89 women) with a mean age of 20.9 years were administered a survey inquiring about the association between each of 86 feelings or actions and four categories of alcoholic beverage (beer, wine, mixed drinks, and straight drinks), assuming comparable levels of intoxication. Multiple discriminant analyses indicated that distinctive and stable expectancies were associated with beer (tension reduction), wine (social pleasure), and straight drinks (mainly negative consequences often related to heavy drinlung), while expectancies for mixed drinks were shared by other beverage types. These findings replicated and extended those obtained with a U.S. s a m p 1 e .

“…7 However, Rencher and Larson [24] have shown that stepwise methods have a high risk of selecting spurious variables, unless the sample size is very large. For this reason we also have estimated 5 This assumption means that the conditional probability P t cannot depend on contemporaneous values of the components of the vector of explanatory variables.…”

a b s t r a c tIn this paper we analyze the factors behind the adoption of Feedein Tariff and we estimate the probabilities that countries not yet adopted the FiT will propose it under different scenario hypotheses. We estimate a panel probit model to a set of 43 countries using annual data covering the period 1980e2008. We employ the binary time series of adoption of the FeedeineTariff as outcome variable and control for a set of economics, environmental and generation factors. Results demonstrate that adoption of FiT depends by various factors. Furthermore, we highlights that one of the main factors is the economic growth. The frequency with which the developed countries adopt the FiT is significantly higher than in developing countries and the probability to adopt FiT increases as income grows up.

“…Consequently, selecting a best subset of h values before performing discrimination is generally an attractive classification strategy. We implemented this strategy by invoking the Wilks-Lambda analysis (Rencher & Larson, 1980). The second problem was concerned with the covariance matrices which were not equal or heteroscedastic.…”
