22  motivation

See the temperatures for Jerusalem in a 4-day interval:

22.1 questions

  • If I know the temperature right now, what does that tell me about the temperature 10 minutes from now? How about 100 minutes? 1000 minutes?

  • The same applies to the past: how heavily does past information inform today’s measurements?

  • information degradation: how fast does information from a signal degrade, and gets swamped by noise?

22.2 goals

  • discuss what is noise, signal, trend, cycles, etc.
  • learn a useful framework to make sense of all the above.
  • acquire statistical and time-series tools to analyze my data
  • eventually, all the above will be crucial to forcast future states.
