Suggested Report Structure for the Group Research Project1. Executive SummaryTip: Provides a precise, succinct, very short (appr. half a page) summary of the research and your keyfindings. The challenge is to provide comprehensive insight for someone who learns about yourproject for the very first time but has not enough time to read the full report.  2. Research Background and ObjectivesTip: Please describe the research background and define the research goal accordingly. Chapter 1should also contain a short outlook on the structure of the report.3. Description of SampleTip: Provide a quick overview over the data.It is important to note that the dataset contains raw data. Please transform the data such that it canbe used for further analysis. For instance, if a variable is “measured” by “no” and “yes” we want totransform that into numbers as this is what R can process. The most intuitive way to code this wouldbe coding “No” as “0” and “Yes” as “1”, that is you create a dummy/binary variable. Further, pleaseremember that categorial and ordinal variables with more than 2 groups should not be used forregression analysis. You therefore do have to recode all variables that you want to use that arecategorial and do have more than 2 categories as dummy/binary variables (be aware of the dummyvariable trap!). Make sure you do this for all variables where it is required.Please also note that it is important to consider which variables could be particularly meaningful forthe purpose of your research and why. Are there variables that are not so meaningful to include inthe model?4. Methodological ApproachTip: Please explain your analysis approach in general. Explain代写Structure、代做R编程设计、R语言代写、代做Re the advantages of the approach ingeneral. Then be more specific and describe the model chosen in your report. It is particularlyimportant to try and address the research goals through the inclusion of relevant variables. Alwaysexplain why you made a specific choice!5. Results  Tip: Unlike the group research report your audience now includes marketing analysts which hasimportant implications for the results section. The report should contain enough information tounderstand how you chose the final model and how you evaluate its fit.It is also important to clarify and explain in detail how the model helps to address the managerialproblems reflected in the research goals (finetune the campaign, target prospects, derive maximumcosts). So these research goals should be addressed in this section.  At a side note, for the implications about campaign finetuning, you may want to derive standardizedeffects (reconsider what standardized effects tell us). We have not done this in the tutorial for theIogistic regression; you can do it by installing and loading the “reghelper” package and then usingthe following command: beta(x), where x is your chosen model. Also make sure that  Further to translate key findings to managers, in this section presentation and visualization helps alot.6. ConclusionTip: Point to the most important conclusions that can be drawn from your analysis and that arerelevant for your audience. It is best to split your conclusions into one part addressed at marketinganalysts and one part addressed at managers. It is also important to point out what conclusionscannot be drawn from your analysis so that managers can make a well‐informed decision.转自：http://www.daixie0.com/contents/18/4360.html
