Detailed explanation1: The objective of factorial analysis is to define a data model with the minimum number of input variables, each of which provides the maximum informative value with respect to a given business objective, which is the output of the model.
Detailed explanation2: We use factorial analysis to know the difference among the many variables.
Detailed explanation3: Factor analysis (FA) is a multivariate technique that is used to describe the relationships between different variables under study (observable variables) with new variables called factors, where the number of factors is less than the number of original variables.
Detailed explanation4: in “factor analysis", “factor” is a variable calculated from several other variables. As said that is a tool to reduce the dimension of many original variables in a few “factors". In “factorial analysis", “factors” refers to (often categorical) predictors.
