Making a prediction?
Something to forecast?
Milton Friedman (deceased now), distinguished economist and notably conservative when it came to finances has this advice
If you're going to predict, then predict often!
Yes, it's a bit humorous. But it's also true, to wit: the future is uncertain, subject to change, and subject to change unexpectedly and perhaps even near-term. So, Friedman might have said:
- Sampling theory tells us to same at least twice as fast as the changing situation we're engaged with.
- If we can't reasonably estimate whether change is linear or exponential, then "sample early; sample often"
- Long-term predictions are of low value (See: sampling theory, above)
