'''Preference regression''' is a statistical technique used by marketers to determine consumers’ [[preferred]] core benefits. It usually supplements [[positioning (marketing)| product positioning]] techniques like [[multi dimensional scaling (in marketing)|multi dimensional scaling]] or [[factor analysis]] and is used to create ideal vectors on [[perceptual mapping|perceptual maps]]. <BR><BR>

Next they regress the survey data against the dimensions. The independent variables are the data collected in the survey. The dependent variable is the preference datum. Like all regression methods, the computer fits weights to best predict data. The resultant regression line is referred to as an ideal vector because the slope of the vector is the ratio of the preferences for the two dimensions.
