I assume that oil price partially depend on weather information. Since future weather is predictable to a large degree, I figure that if we can find the âdependenceâ of oil price against âweatherâ, we shall have some edge. Then, these are two sequences of data. One sequence is the historical weather information, another is historical oil price. What will be the methods to âdiscoverâ the dependence of oil price vs. weather ? (I heard the terms of Factor Analysis or Principle Component Analysis, but not sure if they will be the right tools for the job). Thanks.
