Question: Perform another imputation on the data, this time using a sequential hot-deck procedure. Impute the value of the household immediately preceding the one with the missing item (if that one also has missing data, move up through the previous households until you find one that has the data and then impute that value). How does the value using this imputation scheme differ from the estimate in Exercise?
Exercise: Generate another set of data from the same address list, this time with a 30% item nonresponse rate. (The nonresponse parameters are 0, .3, 0.) What is the average price the respondents are willing to pay for cable? Using the respondents, develop a regression model for cable price based on the other variables. Impute the predicted values from this model for your missing observations and recalculate your estimate.
