The aims of these blog posts are the following:

  • To describe main features of monthly catering time series
  • To model series using popular time series models
  • To forecast future catering time series values
  • To compare forecasting performance of different time series models

Column names in csv file are: Catcur (catering in current prices) and Catcon (catering in constant prices). Those familiar with R could download and use RData file.
