For each of the following, explain what is wrong and why.
a)
If
b
1
= 5
in a logistic regression analysis with one explanatory variable, we estimate that the probability
of an
event is multiplied by 5 when the value of the explanatory variable increases by one unit.
b) The intercept
b
0
is equal to the odds of an event when
x
= 0
.
c) The odds of an event are 1 minus the probability of the event.

12.4 For each of the following, explain what is wrong and why. (a) (1m) A 95% confidence interval for the mean response is the same width regardless of the value of x. (b) (1m) To test H0: b1 = 0, use a t test. (c) (1m) For a particular value of the explanatory variable x, the confidence interval for the mean response will be wider than the prediction interval for a future observation

Suppose we have data on the number of U.S. recruits who were rejected for service in a war against Spain because they did not have enough teeth. We wish to compare the rejection rate for recruits who were under the age of 20 with the rate for those who were 40 or over. To run a logistic regression for this setting, we define an indicator explanatory variable x with values 0 for age under 20 and 1 for age 40...

e) In a simple linear regression model with explanatory variable x and outcome variable y, we have these summary statisties z-10, s/-3 sy-5 and у-20. For a new data point with x = 13, it is possible that the predicted value is y = 26. f A standard multiple regression model with continuous predictors and r2, a categorical predictor T with four values, an interaction between a and...

2.81 What’s wrong? Each of the following statements contains an error. Describe each error and explain why the statement is wrong. A negative relationship is always due to causation. A lurking variable is always a quantitative variable. If the residuals are all negative, this implies that there is a negative relationship between the response variable and the explanatory variable.
