ST2195 The 2009 ASA Statistical Computing and Graphics Data Expo consisted of flight arrival: Coursework Project, SUSS, Singapore

Part 2

The 2009 ASA Statistical Computing and Graphics Data Expo consisted of flight arrival and departure details for all commercial flights on major carriers within the USA from October 1987 to April 2008. This is a large dataset; there are nearly 120 million records in total, and it takes up 1.6 gigabytes of space when compressed and 12 gigabytes when uncompressed. The complete dataset, along with supplementary information and variable
descriptions can be downloaded from the Harvard Dataverse at https://doi.org/10.7910/DVN/HG7NV7
Choose any subset of ten consecutive years and any of the supplementary information provided by the Harvard Dataverse to answer the following questions using the principles and tools you have learned in this course:

(a) What are the best times and days of the week to minimise delays each year?
(b) Evaluate whether older planes suffer more delays on a year-to-year basis.
(c) For each year, fit a logistic regression model for the probability of diverted US flights using as many features as possible from attributes of the departure date, the scheduled departure and arrival times, the coordinates and distance between departure and planned arrival airports, and the carrier. Visualize the coefficients across years.

General Instructions

• All questions should be answered using R and Python for all tasks.

• Your answers should be provided in a separate structured report of no more than 1 page for part 1 and 6 pages for part 2. The page limit excludes titles, references, and table of contents but includes graphics and tables. The report should be in PDF format and also contain adequate explanations for readers not familiar with programming. In addition to the report, you will also be asked to provide your R and Python code in RMarkdown and Jupyter notebooks, respectively. All the relevant files must be submitted in the designated Atrio or VLE submission portal.

• For part 2, each report should detail all steps you took starting from raw data up to the answer for each question. Any databases you set up, data wrangling/cleaning operations you carry out, and any modeling decisions you make should be clearly described in each structured report. Each report should also include any relevant graphics and tables as part of the answer.

• If you are using elements (e.g. code, databases, graphics, etc) from your answer to a previous question to answer the current one, you will need to refer to those elements.

• You should also supply the code you used to answer each question, in a way that can be used by someone else to replicate your analyses. You can do this either as separate scripts or separate RMarkdown/Jupyter notebooks per question, clearly indicating (both with comments and in the filename) which question each script refers to.
