II. You are given the following linear regression model, where ??2 represents a qualitative variable with two outcomes {0,1} and ??1 is a quantitative variable:

?? = ?0 + ?1??1 + ?2??2 + ?i

1. The response function for Y using ??2 = 0 is: (5pts)

2. The response function for Y using ??2 = 1 is: (5pts)

3. Explain theoretically what does

a) ?1 indicates. (10pts)

b) ?0 indicates (10pts)

c) ?2 indicates (10pts)

The statistical model for simple linear regression is written as μy = β0 + β1*x, where μy represents the mean of a Normally distributed response variable and x represents the explanatory variable. The parameters β0 and β1 are estimated, giving the linear regression model defined by μy = 70 + 10*x , with standard deviation σ = 5. (multiple choice question) What is the distribution of the test statistic used to test the null hypothesis H0 : β1 = 0...

The data file Demographics was used in a simple linear regression model where Unemployment Rate is the response variable and Cost of Living is the explanatory variable. You may refer to the previous two questions for the regression model if you wish. The anova function in R was used to obtain the breakdown of the sums of squares for the regression model. This is shown below: > anova(myreg)Analysis of Variance Table Response: Unemployment Df Sum Sq Mean Sq F value...

Two simple (i.e, one x variable) linear regression models are fit. Model A, using variable x1 only, has an R2 of 0.23. Model B, using variable x2 only, has an R2 of 0.57. What will the R2 value be for Model C, which uses both x1 and x2? Cannot be determined without knowing the correlation between x1 and x2. It will be some value less than 0. It will equal 0.34 It will equal 0.80. We cannot say without knowing...
