ECON1203 Business and Economic Statistics

提示:您可能会在调查中追求的一些想法您可以在多元线性回归的情况下解决此里程碑中的所有点。
在回归中添加控件和变量将使您可以沿其分组特征。
作为报告要求的一部分,请说明您的假设。记得显示所有工作。
请记住,这是您要处理真实数据集的一种研究活动。

没有正确或错误的答案。但是统计技术使用不正确,假设。更糟糕的是,对结果的错误解释会误导董事会!的后者是我们要学习避免的东西。
对于线性回归,请报告以下内容:
•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。

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
on your first milestone and any feedback received.
• Section 2 (using Milestone 2) comprises a summary of statistical tests conducted based on
your second milestone and any feedback received.
• 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.
