ANSWER ALL QUESTIONS

Write a Stata program to do the following [3 marks]

a. Take a subsample of the data 500 times b. Compute the mean and the variance of a given continuous variable from each of the subsample c. Compute the grand mean (i.e. overall mean of the means computed from each subsample), and the variance of the mean and the mean of the variance. Now it should add these two variances to compute the grand variance. d. In the output return it must present the grand mean and the grand variance. All these steps must be done quietly.

 

For this exercise use the nlsw88 data and the continuous variable to be used is wage. i) Using foreach loop, create and combine the histogram plots of all the following variables (Age in Current year, Current grade completed, Industry, Occupation, Hourly wage, Usual hours worked, Total work experience, Job tenure) in the nlsw88 data (system data, can all this using sysuse nlsw88).

 

Using the graph editor then add the title and subtitle of your graph. Record these commands required to add title and subtitle to the overall combined graph. Once this is done copy the recorded commands into your do file with the gr_edit command in front of the commands and rerun to the whole code to check if this produces the same result (i.e combine multiple histograms and then adding the title and the subtitle to the final graph) if you automate the code. Describe your answer. [2 marks].
