Packet 9: Categorical Data Analysis
- Contigency Tables
- Marginal Association
- Aggregate over third variable
- (n11*n22)/(n12*n21)
- Conditional Association
- Decide yes or no for the given third variable, then only pull those values of the the other 2 variables
- (n11*n22)/(n12*n21)
- Relationships of Variables
- Mutual
- (X,Y,Z)
- glm(count ~ X + Y + Z , family = "poisson")
- Joint
- (X,YZ)
- glm(count ~ X + Y + Z + YZ , family = "poisson")
- Conditional
- (XY,XZ)
- glm(count ~ X + Y + Z + XY + XZ, family = "poisson")
- Saturated
- (XYZ)
- glm(count ~ X + Y + Z + YZ + XY + XZ + XYZ , family = "poisson")
- Uniform Association
- (XY,YZ,XZ)
- glm(count ~ X + Y + Z + YZ + XY + XZ, family = "poisson")
