Suppose it is of interest to estimate the population mean, μ, for a quantitative variable.
Constructing a frequency distribution for a quantitative variable requires more care in defining the classes and the division points between adjacent classes.
Finally, the canopy cover, as a quantitative variable, was measured with one densitometer reading over the 2-m circular plot of each tropical ash individual.
Per blood product, a qualitative variable (transfusion yes or no) and a quantitative variable (amount of product in units) were generated.
This method can be seen as a process of turning a quantitative variable (one internal software class attribute in our case) into a discrete ordinal variable.
They describe the distribution of a quantitative variable in a healthy population, and are often a smooth function of age or another determinant.
Nevertheless, it should be noted that β j for a quantitative variable is one coefficient, while β j for a class variable or an interaction including one or two class variables is a vector of multiple coefficients.
The model parameters include three sets of variables: the amount of snowfall as a quantitative variable, categorized cold as a dummy variable, and an interaction variable formed by the product of these two variables.
In mineral resources evaluation, the joint simulation of a quantitative variable, such as a metal grade, and a categorical variable, such as a rock type, is challenging when one wants to reproduce spatial trends of the rock type domains, a feature that makes a stationarity assumption questionable.
We suggest that by treating the whole genome as a quantitative variable and deriving a genomic phenotype (phenome), we are able to observe epistatic effects among genes that lead to linkage disequilibrium among members of the genomic core.
