Little understanding issue in 8.1 #855

Closed Alexander-Schiendorfer closed 4 years ago

Alexander-Schiendorfer commented 4 years ago

I am a litte confused by the following paragraph

It is much harder to predict tomorrow’s stock prices than to fill in the blanks for a stock price we missed yesterday, even though both are just a matter of estimating one number. After all, hindsight is so much easier than foresight. In statistics the former is called extrapolation whereas the latter is called interpolation.

Isn't the former (hindsight) called intrapolation and the latter (foresight) called extrapolation. So, the other way around?
