The screenshot below shows how we can define a Rank aggregation:
Within the expression we would then select bookings with a Rank = 1, and then add this as a clause to the And() expression in the first example.
These two examples simply give cyprus mobile numbers a flavour of the opportunities that are opened up by this new development, but in reality, there are myriad possibilities of how you might use these aggregations to unlock new details that lie within your data.
The UK Civil Aviation Authority (CAA) (1) produces detailed monthly statistics on a number of topics related to UK airports. In this case study we’ll be using FastStats to analyse how delays to flights in the UK have changed over the past 20 years. We’ll show some interesting trends relating to the number of flights and how this changes throughout the years, and also how this relates to average delays based on a range of factors – such as by airport, flight type, and flight distance.
Data Collection
The hardest part of many data analytics projects is obtaining the raw data and wrangling it into a suitable format for analysis. As of March 2018, the CAA has the data from 1995 to the end of 2017 available on their website in a set of monthly CSV files (2). Each CSV file is an aggregated monthly view of a particular flight route (e.g. Birmingham-Copenhagen for airline X in the month of January 1995).
