This paper estimates a dynamic common factor model to assess relative importance of the aggregate and the sector-specific factors that determine changes in the prices of individual products. It also examines how aggregate price changes are affected by these factors. Two different specifications of the model are estimated: the baseline model with one aggregate factor, and a second specification ...

Importance should indicate the degree to which the attribute is associated with the dependent variable. The first measure, statistical significance, instead only tells us the level of confidence we have in accurately measuring a coefficient of association (i.e. correlation, regression, etc.). Specifically, as sample size increases, statistical significance rises. This reflects the fact that as ...

Neural networks commonly offer high utility but remain difficult to interpret. Developing methods to explain their decisions is challenging due to their large size, complex structure, and inscrutable internal representations. This work argues that the language of explanations should be expanded from that of input features (e.g., assigning importance weightings to pixels) to include that of high...

In response to a mail survey, 225 leading general internists provided their opinions of the relative importance to patients of thirty medical innovations. They also provided information about themselves and their practices. Their responses yielded a mean score and a variability score for each innovation. Mean scores were significantly higher for innovations in procedures than in medications and...

This article looks at the extent to which aged couples and nonmarried persons rely on earnings, retirement pensions, assets, and public assistance. The study notes the importance of these various sources to aged units with different levels of both total money income and retirement income, then examines changes in the relative importance of the different sources over time. The data indicate that...
