## 这个作业是来自澳洲的关于用多元线性回归完成商业问题的统计经济代写，以下是作业具体内容：

•解释系数。
•定义并评论每个系数是否在统计/经济上重大。请记住陈述您的假设。
•模型的局限性和问题。这里主要关注的是多重共线性，同方差，并省略了变量偏差。您需要将这些概念放在问题的背景以及它们如何影响您的统计推断。

Final executive report
The final report unifies all three millstones/sections which you have completed which
showcases all the statistical techniques you have learnt to date. This report is a final take on
this problem and should include the key results that you wish the Board to learn about this
puzzling phenomenon in the labour market. Your report will consist of five core sections:
• Introduction and executive summary (1/2 page max for executive summary).
• Section 1 (using Milestone 1) which comprises a summary of key features of data based
• Section 2 (using Milestone 2) comprises a summary of statistical tests conducted based on
• Section 3 (using Milestone 3) will investigate the productivity story in the claims above.
• Concluding remarks.
Please note that Section 1 and Section 2 is not a copy/paste of all your reports for the first two
milestones. These sections should report the take home messages from your detailed analysis
that you have completed. No need to re-report the tables and graphs from those milestones.
You should summarize the key points and state briefly the statistical evidence/argument that
support those key points.
Your report should tell a story that uses all the key conclusions you have come to from the first
two milestones, and which will probably also inform your analysis for the last milestone.
