- You gave a forecast only for 1 month !!! Based on the task 2 month needed Graph initial and smoothed time series. Does your forecast seem to be reasonable? Explain your answer.arrow_forwardTrue/False Censoring occurs when the event of interest (e.g., disease status) is observed on every individual, usually due to time constraints. The incidence rate (IR), is computed by taking the ratio of the number of new cases of disease to the total number of person-time units available. The prevalence of a disease depends on the incidence of the disease as well as the duration of the disease.arrow_forwardCan you get higher accuracy in the time series regression model than the decision tree model? Also, state an example if this can happen?arrow_forward
- Malak is designing an experiment. In this experiment, he wants know if "learning about sustainable investing" actually causes people to invest more sustainably. He sets up an experiment with two groups: one group receives a course on sustainable investing , the other group does not . Then, over the course of the next 10 years, sustainable investing behavior is measured (so as a researcher Malak keeps track of the participants ' investing behavior with their own money in their life, at yearly intervals , for one decade ).

- For this question, create a new column in the dataset where total rainfall is just the sum of our three separate rainfall variables. (Solve this question by Excel and econmetrics knowlege like time series) (a) plot crop yield vs. time. Does yield appear to be stationary? Why or why not? (b) plot total rainfall vs. time. Does total rainfall appear to be stationary? Why or why not? (c) plot the first-difference of crop yield vs. time. Does this series appear to be stationary? Why or why not? (d) formally test whether crop yield, rainfall and the first-difference of crop yield are stationary using the appropriate test. Be sure to do all parts of the hypothesis tests. After these tests, what can you say the order of integration is for each of the variables?(e) estimate a model where yield is a function of rainfall and time. You do not have to worry about the time variable being stationary or not, but the other two must be stationary (you might need to difference one or both of them to…arrow_forwardTime series data usually shows a pattern, which is caused by a systematic and unsystematic pattern.
