题干

Wilson answers that simulation is better and the data collection process will be valuable to PCS because it may want to evaluate these same countries in future years. She offers to collect the data for the analysis and decides that GDP growth rate, unemployment rate, the 10-year government bond rate, and the inflation rate would probably explain stock index returns. Wilson wants to be sure she correctly defines the probability distributions because that is a key step in the analysis. Consequently, she considers

  • increasing the number of variables in the simulation,
  • using variables that are linearly related to each other to increase the estimation accuracy, and
  • directly estimating the statistical parameters of her variables.




问题:Given Wilson’s alternatives for defining the probability distribution, her best choice would be to focus on:

  1. selecting variables that are linearly related.
  2. the number of variables.
  3. direct estimation.
