Least square estimators
1. You should work in pairs. Try the following for
- First, you pick a parameter and and generate a sample of size using the formula:
Use random values for in the range that you like. For the error , you can generate a random error based on a normal distributions.
- Give the data to your partner.
- After you get the data from your friend, find the least square estimators for and
