Given information
An economist is deriving a model to predict outcomes on the stock market. He creates a list of expected points on the stock market index for the next two weeks. At the close of each day’s trading, he records the actual points on the index. He wants to see how well his model matched what actually happened.
Step-by-step explanation
As stated in the problem, the economist creates the list of expected points on the stock market index for the next two weeks coming up and also records the actual points at the end of each day’s trading.
In order to compare the actual points with the expected points so as to match the model he created. Therefore, in this study economists, can apply the goodness-of-fit test.
Hence, the goodness-of-fit test is the most appropriate test that can be applied in the given scenario.
