How does utilizing linear regression benefit or help a business?

Many institutes, departments, and recruitment committees are using citations as part of the assessment process involved in making new appointments. By going through scientific databases like Scopusselection panels can check if a candidate’s work is making an impact by being cited by other researchers in their field. How does the scientific community measure how "good" or "great" a journal or an author is? How do you determine the "impact" of an author's work? The most 2common metric to track an author's impact is ask how often they are cited. The following table presents the number of citation on research publications of two Management Science professors over a period of 17years, 2005 to 2021, data taken from Google Scholar. The objective of this assignment is to find a suitable forecasting method (moving average, exponential smoothing, and/or simple linear regression model) to predict near future citation of a researcher.  (a) For each professor, develop a scatter diagram on his…
