Question Answered step-by-step The researchers would like to express model (1) in matrix form, Yi… The researchers would like to express model (1) in matrix form, Yi = Xi ? + Zi µi + ?i , where Yi represents the response vector for subject i, Xi represents a matrix, for subject i, that contains the values of the predictors associated with the fixed effects of model (1), ? is the fixed effect vector, Zi is a matrix, for subject i, that contains the values of the predictors associated with the random effects of model (1), µi is the random effect vector for subject i and ?i is the random error vector for subject i. Answer the following questions. (a) Write down the response vector, Yi , of model (1), for subject i. (1 mark) (b) Write down the matrix, Xi , of model (1), for subject i. (5 marks) (c) Write down the fixed effect vector, ?, of model (1). (1 mark) (d) Write down the matrix, Zi , of model (1), for subject i. (2 marks) (e) Write down the random effect vector, µi , of model (1), for subject i. (1 mark) (f) Write down the random error vector, ?i , of model (1), for subject i. (1 mark) 2. Interpret the fixed effects ?0, ?2 and ?9.
