We need an R Program and PPT for below questions.
Report the findings in a presentation.
Problem: Ideally, life expectancy would be the same for all people throughout the world. On the global
scale, the average longevity is rising, but gaps between differing life expectancies are significant
(Helliwell et al., 2020). Varying social environments and the interplay of differing life
expectancies have not been examined in the research. Unearthing influential characteristics can
provide new insight to close the gaps.
1) What is the most influential characteristic in predicting the purchasing power parity, also
known as the gross domestic product per capita, amongst the surveyed responses that amount
to specific metrics in the World Happiness Report for 2020:
• social support;
• satisfaction with the freedom to choose what to do with one’s life; and
• respondents that donate to charity;
• the perception of corruption in the government and businesses; and
• respondents amount of laughter and enjoyment on a day-to-day basis;
• along with those respondents’ answers regarding worry, sadness, and anger; and
• the responses regarding confidence in the national government;
• perceptions of democratic quality, measured via people’s voice and officials’ accountability,
and political stability evidenced by the absence of violence; and
• delivery quality, measured by the responses to government effectiveness, regulatory quality,
and the effectiveness of law and order, and the effectiveness in controlling corruption?
2) Using different regression methods, quantile random forest and traditional random forest
modeling produces different results. Using these methods of analysis, what aspect of the
modeling generates different results with the World Happiness Report data for 2020 analysis?
Objective: Using a quantile regression random forest model and the traditional modeling via random forest,
answer the research questions. The discussion around the second research question will not be
written or addressed like directions from a book, because it will be addressed and explained in
terms of this data specifically.
• The World Happiness Report is published annually. This research will utilize the data from 2020.
• Helliwell, J. F., Layard, R., Sachs, J., & De Neve, J.-E. (Eds.). (2020). World happiness report 2020.
