The importance of blood pressure variability in hypertension
Blood Pressure Monitoring, 2000Use of ambulatory blood pressure monitoring (ABPM) techniques has revealed that blood pressure is characterized by a considerable degree of variability over a 24 h period as a result, not only of the well-known fluctuations that occur between wakefulness and sleep, but also of the minute-to-minute changes induced by a variety of behavioural conditions.

The Importance of Socioeconomic Variables
1996So far in the book, we have mainly estimated elasticities based on aggregate time-series data. In Chapter 9 we also applied household data, but the micro model used there only allowed a limited amount of taste variation across households. That model, for example, neglected any interaction between economic and socioeconomic variables, and assumed ...

Perimetric variability: Importance of criterion level
Documenta Ophthalmologica, 1988Perimetry suffers from considerable variability of results. A new technique for estimating individual criterion levels in normal subjects exposes the important role of psychological variables. The analysis depends on features peculiar to acuity perimetry. It can be accommodated in the regular examination.

Variable importance in latent variable regression models
Journal of Chemometrics, 2014The quality and practical usefulness of a regression model are a function of both interpretability and prediction performance. This work presents some new graphical tools for improved interpretation of latent variable regression models that can also assist in improved algorithms for variable selection.

Variable importance assessment in sliced inverse regression for variable selection
Communications in Statistics - Simulation and Computation, 2017The focus is on treating the relationship between a dependent variable $y$ and a $p$-dimensional covariate $x$ in a semiparametric regression model. Since the purpose of most social, biological or environmental science research is the explanation, the determination of the importance of the variables is a major concern.

A LINGUISTIC VARIABLE FOR IMPORTANCE OF FUZZY SETS
Journal of Cybernetics, 1980In this paper we introduce the concept of a linguistic variable for importance. This is done by defining its linguistic values as fuzzy subsets over the set of nonnegative numbers. Furthermore, we show how to modify a fuzzy subset by its importance. That is, if A is a fuzzy subset of X, and / is its importance, then A becomes AI which is also a fuzzy ...

TIME: AN IMPORTANT VARIABLE AT CAESAREAN SECTION
BJOG: An International Journal of Obstetrics & Gynaecology, 1970SummaryBiochemical evidence of fetal asphyxia (relative hypoxia with hypercapnia) and acidaemia has been found in the cord blood of infants delivered by Caesarean section in a series of patients who had been selected to exclude complications of pregnancy which prejudiced the fetal condition before or during anaesthesia.

A Test for Variable Importance
2018Statistical literature is being more and more concerned with debates about hypothesis testing and p-values supporting the significance of a given variable specification. Specifically, if on one hand statistical foundations about significance are not arguable, scholars should be able to distinguish between significance and variable importance. This is a
