Conditional Log-linear Structures for Log-linear Modelling

Hybrid of tree and log-linear structures, Strong hierarchy principle, Variable-removal, Zero-w phenomenon.


A log-linear modelling will take quite a long time if the data involves many variables and if we try to deal with all the variables at once. [1] investigated the relationship between log-linear model and its conditional, and we will show how this relationship is employed for finding the actual model structure based on a collection of conditional log-linear structures. We show that parts of model structure can be read from conditional model structures and so that we can find the actual model structure by putting the conditional log-linear structures together as long as the conditionals are col lected under some condition. The result of this article can be applied for modelling all the hierarchical log linear models.
