1. If you were to graph a time series and it followed a trend that was close to linear, then what type of forecasting model would you use?

Multiple Choice

  • Bass model

  • Bivariate linear regression

  • Simple moving average

  • Gompertz curve

2. Visualization of data allows you to ____________________.

Multiple Choice

  • be as transparent to management as required

  • more clearly identify the dependent and independent variables

  • better understand if you need more data

  • see stark differences that would not be apparent from the descriptive statistics

3. What is the primary purpose of the third step when you are evaluating a linear regression model?

Multiple Choice

  • To evaluate the explanatory power of the model.

  • To understand whether the relationship is statistically significant at the desired level of confidence.

  • To determine if the model has negative serial correlation.

  • To assess whether the model is logical.

4. What is the best way to decide on whether a linear or nonlinear model would be most appropriate?

Multiple Choice

  • An evaluation of the subsample of the historical data.

  • A forecast of the independent variables.

  • A review of the dependent variable, the series to be forecast, and the independent variable(s).

  • A visual inspection of the data in a graphical format.

5. What assumption does the causal model make?

Multiple Choice

  • Changes in the dependent variable will cause changes to other dependent variables.

  • Changes in the independent variable will cause a change in the variable to be forecast.

  • No changes occur.

  • Changes only occur in the variable to be forecast, but that change is not related to the independent variable.

Answer #1

As per the HOMEWORKLIB RULES, we are allowed to answer 1 question, in case of multiple questions being asked or else we will be revoked, sorry.

Question 1

For time series data, Gompertz curve is the best fit model. Gompertz function is a type of mathematical model for a time series, named after Benjamin Gompertz (1779-1865). It describes growth as being slowest at the start and end of a given time period.

Hence, the correct option will be Gompertz Curve.

    How does a regression plane differ from a regression line? Multiple Choice A regression plane represents a two-dimensional space (e.g. one dependent and one independent variable) whereas a regression line represents a three-dimensional space (e.g. one dependent and two independent variables). A regression plane represents a three-dimensional space (e.g. one dependent and two independent variables) whereas a regression line represents a two-dimensional space (e.g. one dependent and one independent variable). A regression plane can represent a bivariate regression model and...

    According to the book, what should you consider if you are selecting independent variables for a multiple regression model? Multiple Choice The logical selection will be based on the algebraic sign for each variable in the model. The overlap in two or more independent variables will influence the dependent variable. The coefficient of determination should be used to determine the explanatory power of the model. The selection should be based on an understanding of the nature of the situation
