If Yi = 1.1 + 2.5xi + εi, εi ∼ N(0, 1.7) is a regression model with independent errors, find (a) The distribution of Y1 − Y2 when Y1 corresponds to x1 = 3 and Y2 corresponds to x2 = 4. (b) P(Y1 > Y2)
Added by Tamara S.
Step 1
Given the model \( Y_i = 1.1 + 2.5x_i + \epsilon_i \), we can write: - For \( Y_1 \) when \( x_1 = 3 \): \[ Y_1 = 1.1 + 2.5(3) + \epsilon_1 = 1.1 + 7.5 + \epsilon_1 = 8.6 + \epsilon_1 \] - For \( Y_2 \) when \( x_2 = 4 \): \[ Y_2 = 1.1 + 2.5(4) + Show more…

A. Which of the following models are linear? If a model is non-linear, indicate the non-linear term. I. y = ̠₀(̠₁x₁ + ̠₂x₂) + ̠ II. y = ̠₁(x₁ – x̄₁) + ̠₂(x₂ – x̄₂) + ̠ III. y = exp(̠₀ + ̠₁x) + ̠ IV. y = ̠₀ + ̠₁x₁" + ̠₂x₂" + ̠ B. Write the corresponding mathematical models for the following linear models in "R": I. lm( y ~ x1 : x2 ) II. lm( y ~ I(1/x) + I(x^3) ) C. Let Y₁ ∼ N(2, 2) , Y₂ ∼ N(−4, 2) , Y₃ ∼ N(−2, 2) and Y₄ ∼ N(2, 4) be independent random variables. Answer the following questions and explain your workings. I. Find the distributions of X₁ = 2Y₁ + Y₂ and X₂ = Y₁ − 2Y₃ II. Construct two independent random variables Z₁ = Z₁(Y₁, Y₂, Y₃, Y₄) and Z₂ = Z₂(Y₁, Y₂, Y₃, Y₄) such that Z₁ ∼ χ²₃ and Z₂ ∼ χ²₁ III. Construct a random variable W = W(Y₁, Y₂, Y₃, Y₄) such that W ∼ F₃,₁ D. Briefly explain what are the standard assumptions on random errors in the simple linear regression model.
