Question

What is a loglinear model in categorical data analysis?

Answer 1

Answer:
  log linear model in categorical data analysis:

  Log-linear models go beyond a single summary statistics and specify how the cell counts depend on the levels of categorical variables

  The log-linear modeling is natural for Poisson, Multi nomial and Product-Mutlinomial sampling.

  They model the association and interaction patterns among categorical variables.

Thus far in the course we have alluded to log-linear models several times, but have never got down to the basics of it.

  Log-linear models go beyond a single summary statistics and specify how the cell counts depend on the levels of categorical variables.

  single summary statistics, and with significance testing

log it model for A with only an intercept;

log it model for A with a main effect for D;

log it model for A with a main effect for S;

log it model for A with a main effects for D and S; and

log it model for A with main effects for D and S and the D × S interaction.
