Here is my question.

3. (Fox 6.5) Maximum likelihood estimation of the simpleregression model: Under all linear model assumptions, the Ks are independently normally distributed random variables with mean 01+ 53:1- and common variance 0?. Show that if these assumptions hold then the leastsquares coeicients A and B are the MLEs of a and B and that 5'3 : Z EE is the MLE of 03. Note that the MLE of the error variance is biased. Hints: Note that the joint probability density for the YES is a product of their marginals under independence. The marginals are: 1 (3h (06 + 5%))2 Mm) = To? exp 203 Take the log of the product to get the loglikelihood. It is simpler to optimize the loglikelihood using calculus
