4. Suppose the panel data model is given by: where Z, is not observed, i 1,, n and t - 1,2,3. In this model we have three waves or we have three cross-sectional data sets: Now we assign the weight 1/2, 1/3, 1/6 to wave 1, wave 2 and wave 3, respectively, i.e., the first wave receives a larger weight while the third wave gets less weight. Please propose a feasible "difference" type estimator for 3, 4. Suppose the panel...

Assume that we have three independent observations: where Xi ~ Binomial(n 7,p) for i E { 1.2.3). The value of p E (0, 1) is not known. When we have observations like this from different, independent ran- dom variables, we can find joint probabilities by multiplying together th ndividual probabilities. For example This should remind you the discussion on statistical independence of random variables that can be found in the course book (see page 22) Answer the following questions a...

In this problem, we will model the likelihood of a particular client of a financial firm defaulting on his or her loans based on previous transactions. There are only two outcomes, "Yes" or "No", depending on whether the client eventually defaults or not. It is believed that the client's current balance is a good predictor for this outcome, so that the more money is spent without paying, the more likely it is for that person to default. For each x,...
