2025/2/8 CPI calculation formula
Previously I once pasted the Laspeyres formula for “consumer price index” on LINE, saying that CPI is viewed using the Laspeyres method.
At that time I was in the process of creating an explanation of the Laspeyres formula, but I thought, “Even if I upload this, it won’t allow me to predict CPI, so it’s meaningless,” and I stopped the explanation part halfway.
However, after looking at the reviews from everyone, there were many comments addressing “my knowledge,” and I thought, “some readers might enjoy reading the new CPI calculation formula as well,” so I decided to upload it. Therefore, those who are not interested can choose not to read it without any problem.
