  • Make it a habit to examine the residuals of a fitted model, including deviations from a simple mean. Check for normality by making a dot diagram or histogram. Plot the residuals against the predicted values, against the predictor variables, and as a function of the time order in which themeasurements were made

  • Wittman (1941) developed a prognosis scale for predicting outcome of electroshock therapy in schizophrenia, which consisted of 30 variables rated from social history and psychiatric examination. The predictors ranged from semi-objective matters (such as duration of psychosis) to highly interpretive judgments (such as anal-erotic vs. oral-erotic character). None of the predictor variables was psychometric.

  • The employer-employee Relationship: A phenomenological Study of Retention and the Information Technology Worker In University of California data, I find evidence that observable background characteristics—particularly those describing the composition of the school, rather than the individual’s own background—are strong predictors of both SAT scores and collegiate performance, and that much of the SAT’s apparent predictive power derives from its association with these background characteristics.

  • Chronic lymphocytic leukemia (CLL) follows an extremely variable course with survival ranging from months to decades. Recently, there has been major progress in the identification of molecular and cellular markers that may predict the tendency for disease progression in CLL patients. In particular, the mutational profile of Ig genes and some cytogenetic abnormalities have been found to be important predictors of prognosis in CLL. However, this progress has raised new questions about the biology, prognosis and management of the disease, some of which are addressed here. ...

  • The interaction between these two variables, however, provided a better predictor of beverage preference. Similar results, in terms of the interaction between product choice and usage situation were found by Green and Rao (1972), Belk (1974) and Srivastava et al. (1978). In a later study, Srivastava (1980) examined the appropriateness of financial services in a particular situation and found it to be relatively stable across situations, thus providing further support for using consumption situations as a basis for segmenting the market.

  • In a classification problem, you typically have historical data (labeled examples) and unlabeled examples. Each labeled example consists of multiple predictor attributes and one target attribute (dependent variable). The value of the target attribute is a class label. The unlabeled examples consist of the predictor attributes only. The goal of classification is to construct a model using the historical data that accurately predicts the label (class) of the unlabeled examples.

  • Statistical models were used to control for—i.e., remove—the impact of socioeconomic factors that might account for the correlation between race/ethnicity and credit scores. The inclusion of such controls slightly weakened, but by no means eliminated (or accounted for) the association between minority status and credit scores. Among all such control variables, race/ethnicity proved to be the most robust single predictor of credit scores; in most instances it had a significantly greater impact than education, marital status, income and housing values.
