Test for Coincidence Using a Single Regression Model

TEST FOR COINCIDENCE USING A SINGLE REGRESSION MODEL 

Remember that the test for coincidence tests both the intercepts and the slopes for equivalence. The full model is 

If both of these models have the same intercepts and same slopes, then both 2 and 63 must be 0 (Z 2 = 0) and (63 = 0). 

the test hypothesis is whether b2 = t 3 = 0- The partial or reduced model, then, is 

62 = f s = 0. (The microbial reduction data for the two products have the same slope and intercepts.)
