3. [25 points] Suppose that y, and a: are each vectors of length n = 20, and that each element in y strictly positive (i.e., > 0). Another vector (v) is dened within the rst code snippet below. Suppose that the it\" element of vector y (denoted yg), is a realization of random variable Y5. (a) Write down the model and assumptions of "tl " in the 3 components of the GLM. \"rithin your answer express the systematic component in terms of mi (not only in terms of m), where :51- and 1),; represent the 1'\" element of vectors a: and 1.1 respectively. v = exp(x} fitl
