Answer Each Question (3 points each) • Describe the derivation of BP algorithm. • Is BP equal to MLP? • Is BP equal to Supervised learning algorithm?
it is all one question, please answer them all! thank you! 3. Points = 24. Consider Input-Output Model: Input matrix: A= r 0.05 0.33 0.19 0.25 0.10 0.38 0.34 1 0.12 0 Final-demand vector: r 1800 d= [ 200 900 1) Explain economic meaning of the elements 0.25, 0, and 900. (3 points) 2) Explain the economic meaning of the second-column sum. (3 points) 3) Write out the specific input-output matrix equation for this model. (2 points) 4) Solve the...
Question 10 (4 points) Although all protein structures are unique, there are common structural building blocks that are referred to as regular secondary structures, Some proteins have alpha-helices, some have beta-sheets, and still others have a combination of both. What makes it possible for proteins to have these common structural elements? 12 15 a) the hydrophobic-core interactions. b) hydrogen bonds that form along (alpha helices) or between (beta sheets) polypeptide backbones. c) side-chain interactions d) specific amino acid sequences. 7...
ignore “our model” in the instructions 4. In our model of decision making, grade points and free time are scarce. Describe a situation in which Carla's grade points and free time would not be scarce. Remember, scarcity depends on both his preferences and the production function. 4. In our model of decision making, grade points and free time are scarce.

Question 2 (10 points) In your own words, describe the MARS model of individual behaviour. Provide an example.
Question 1 (a) (4 points) What are they key advantages of the Logit model over the Linear Probability Model? (b) (15 points) In class we saw that efficient estimates of the coefficients from a linear regression model can be obtained under the presence of heteroskedasticity using Generalized Least Squares (GLS). How does GLS work? That is, describe the mechanism through which GLS addresses non-constant error variances to achieve efficient estimation. (c) (5 points) Let Zi be the log-odds ratio in...
