With inflation and the impact of higher prices on households' cost of living under the spotlight, the Office for National Statistics(ONS) announced changes to the 2022 basket of goods to reflect people's inflation experiences in the UK, in line with the current circumstances. Below are three regression outputs fitting the consumer prices index (CPI) to a different basket of goods, each basket of goods consists of 50 consumer items.
