Happy to provide a personal guarantee to meet customer needs for the project. Will complete the project using R Studio and Sweave, published through RPubs to provide reproducible analysis that details the methods used. Will provide at least three different charts and/or plots that demonstrate the delays by the criteria you need to see. Need a little clarification on the data fields and exactly what metrics are used for each, including how they are aggregated/averaged, etc. in the existing csv file. Also will need to understand what are the key questions to be addressed: totals, average by month, or airport, or airline, whatever. Can do some exploratory data analysis in early stages of project and share with you to see if we are meeting your expectations.
