Could someone walk me through how to do this? I appreciate as much detail as possible as I am trying to teach myself. Thank you!

For each of the following regression models, write down the response vector Y, the model matrix X, the 3 vector, and the error vector E. Assume in both cases that there are five observations. (a) Yi = BIXil + 32Xi2 + B3X3 + Ei (b) VYi = Bo + BIXil + 32 log10 Xi2 + Ei
