Log-linear model in psychological data analysis

ABSTRACT

A log-linear model, a procedure already discussed by statisticians has often been ignored by researchers in behavioural sciences. According to log linear model the logarithm of the average frequency in the entire population +/- can be expressed as log linear model the logarithm of the average frequency in the entire population x can be expressed as LogX = [A B][ij]+ [A][i] + [B][i] + [Over all Effect]. LogX = [A B][ij][12] + [A][i][1] + [B][i][2] + [A B][0] The analysis of a 2-way contingency table requiring the testing of interaction parameter [A B][ij][12] becomes informative if the log-linear model is used
