FAiR (version 0.4-13)

manifest-class: Class "manifest"

Description

It is not necessary to understand this help page if one merely wants to estimate a factor analysis model. This help page is intended for those who want to modify or extend FAiR or otherwise want some idea of how FAiR works behind the scenes.

This class contains information in its slots about the left-hand side of a factor analysis model.

Objects from the Class

Objects can be created by calls of the form new("manifest", ...). However, it is not recommended to do so in normal usage since make_manifest provides the constructor for users.

Details

In the future, the advantages of formal S4 classes will be exploited more fully. For example, to include a new model in FAiR, the first step might be to define a a new class that extends "manifest" if necessary. Then, appropriate methods for this class would need to be written. Here is a table of the class hierarchy: lll{ Class Parent Class Comment "manifest" none none (virtual class) "manifest.basic" "manifest" Can be used for any model "manifest.basic.userW" "manifest.basic" ADF with user-specified weight matrix "manifest.data" "manifest.basic" Can be used for any model "manifest.data.ordinal" "manifest.data" Used when some variables are ordinal "manifest.data.ranks" "manifest.data" Used when variables are converted to their ranks "manifest.data.mcd" "manifest.data" Can be used for any model }
