Finding it difficult to work out how to separate the data. I have 2 variables - time and GDP. There are 478 observations, each of which count for a month of the year (1 observation = 1 month). How am I able to split the data into different sections to view both in-sample data and out-sample data separately?
I need to recreate 2 tables. Table 1 must contain data from 1980-2013 (in-sample period) and Table 2 must show data from 2014 to 2019 (out-sample period).
