Could someone show me how I could create a linear regression
model without any intercepts using Matrix operations. The following
points are: (x1, x2, y): (2, 3, 15), (4, 5, 23), (1, 2, 8), and (3,
5, 21).
How do you create a linear regression model with any intercept
using Matrix operations. The following points are: (x0, x1, x2, y):
(1, 2, 3, 15), (1, 4, 5, 23), (1, 1, 2, 8), and (1, 3, 5, 21).
Hello, I was wondering if someone could show me the process as
to how to answer this question. The answers were posted by the
teacher assistant however I do not actually know how to solve the
question: The production function of a firm is given as ? =K 1/2,
L1/2 , capital is 200. The rental rate for both labor and capital
is 5 and 20. There are total 20 firms that produce the same good.
A. Write down the...
I have the answers listed I just want to know if someone could
show me the work step by step!
Q1. A ball of mass 60 g is dropped from a height of 3.4 m. It
lands on the top of a frictionless ramp at height 1.8 m. The ramp
is tilted at an angle of 20 degrees.
(a) What is the velocity of the ball at the top of the ramp?
Answer: 5.6 m/s
(b) At the bottom of...
without using excel can someone show me the steps to approach
the following question
Question 2 Rump Industries Ltd expects its new product will give
it a significant first mover advantage in the market and that is
expected to provide growth in earnings per share of 400% within the
coming year, and 75% growth in each of the subsequent 3 years.
After that time, it is expected competitors will have developed and
brought to market similar products with the result...
How do I solve short term load forecasting using Multiple Linear
Regression? Can anyone provide me a step by step guide and
solution? (Please provide a sample data)
Can someone show me how this answer is 8,080 ? I keep coming up
with the wrong number. Stellar Company has the following sales,
variable cost, and fixed cost. If sales increase by $10,000 then
their profit increases/decreases by how much?
Sales $50,000
Variable Costs $9,600
Fixed Costs $29,000
Answer is 8,080
Calculate the total cost of FC and VC for $50,000.
2) Calculate the increase in VC based on the % increase in
Sales. VC/50000 * new sales

One of the benefits of a linear regression model, is that it’s
relatively easy to create a confidence interval on the mean
response. Imagine you created a linear regression model from a
dataset with n = 12, that applies over the range 0.0 ≤ x ≤ 10.0,
where the mean value of x = 5.0 , the fitted model is Y = 74 + 15
x, Sxx = 0.75, and σ2. = 1.5 At what value of x does the...
Can any linear regression model be checked for model adequacy by
statistical testing for lack of fit or goodness of fit? Why or why
not? Please provide your answer with detailed justification (i.e.,
by mathematical proof or by showing a numerical example)
