Frequency and percentage were calculated for qualitative variables while mean and standard deviation (SD) were calculated for quantitative variable.
When M is a quantitative variable, the most usual (albeit arbitrary) values are the sample mean (zero, when the model is mean centered) and the points located at one standard deviation below and above the mean.
Many of the quantitative variable have broad overlap between normal patients and glaucoma patients, he says, and though qualitative variables have a higher specificity, some may only be significant when they appear with others.
For example, instead of defining a boolean variable [BMI.sub.[less than or equal to]25] (see Table 4), we take the quantitative variable BMI and generate all the possible evaluative linguistic predications and define fuzzy sets [BMI.sub.ExSm], [BMI.sub.SiSm], [BMI.sub.VeSm], [BMI.sub.Sm], ..., [BMI.sub.VRSm], so that the first column in Table 4 is replaced with Table 5.

The categorical factor analysis, usually referred to as item factor analysis (Bock & Gibbons, 2010; Wirth & Edwards, 2007), assumes that observed data originate from a discretization of an underlying quantitative variable. Consider the linear factor model defined in Equation (1).
