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.
