Which of the following statements are not true? The way to incorporate a qualitative (categorical) variable with three possible categories into a regression model is to define a single-numerical variable with coded values such as 0, 1, and 2 corresponding to the three categories. Incorporating a categorical variable with c possible categories into a multiple regression model requires the use of c-1 indicator variables. The positive square root of the coefficient of multiple determination is called the multiple correlation coefficient R.

6. In a logistic regression model, only one independent variable is allowed. The dependent variable has to be a qualitative dichotomous variable, and the independent variables can be of any type. 7. The OR (odds ratio) can be obtained by starting from the coefficient corresponding to the independent variable (exposure) in a logistic regression model. 8. The Chi-Squared test is used for data that represent counts exclusively organized in 2x2 contingency tables.

Fill in the blanks below. If we do not observe both dependent and explanatory variables for a group of observations, the dataset is called _(i)_. If we do not observe independent variable but have explanatory variables, the dataset is called _(ii)_. Suppose you are interested in the determinants of bond ratings of 500 listed companies. Bond ratings can be described in the following discrete scale. Which of the following is the correct description of the type of the dependent variable? (a) Count variable (b) Binary variable (c) Unordered multinomial variable (d) Ordered multinomial variable (e) Continuous variable. Which of the following is the correct combination of the name and interpretation of λ(xβ/σ)? Name: Interpretation. Which of the following is the correct description of the type of the dependent variable in the relationship between high school students' characteristics and choice of colleges? (a) Count variable (b) Binary variable (c) Unordered multinomial variable (d) Ordered multinomial variable (e) Continuous variable. The maximum likelihood estimator with unordered choice can be derived from. You are interested in the relationship between the number of patents acquired by a firm in a year and firm's characteristics. Which of the following is appropriate in estimating the relationship? (a) Only the Poisson model (b) Only the negative binomial model (c) Only the random utility model (d) Either the Poisson model or the negative binomial model
