Question
The following data are obtained during an experiment involving 2 independent variables, y being the measured response. It is assumed that the intercept π½0 = 0 and the relationship is linear
with 2 parameters y = π½1x1 + π½2x2. 1. What is the associated least squares optimization problem? 2. Determine the model parameters. 3. What is the predicted value for xβ = 3, xβ = 1? 4. How would the problem be modified to include an interaction between the 2 predictors?
