ARE 106 Econometrics Homework 2 Winter 2009 A. Havenner Eight problems on two pages. Computer Problems: The intent here is to get you to look around in Gretl in the context of a particular dataset andjust generally become familiar with it by clicking various tabs and seeing what you get. Create a Word document to post various results into as you do the exercises below, and then print it and turn it in with your name clearly typed or written on top so we can get an accurate gradesheet going. (Your student number is not necessary.) 1. The data file data2-2 contains data on high school and college grade point averages for 427 students who entered college in Fall, 1985. 1 (i) Use "DatalRead info" to see what these data are. Copy and paste this information into your results document (for Windows, select text with the mouse then use CTRL C to copy). (ii) Is this a time series dataset or a cross section dataset? (iii) It is always good to look at the actual data whenever possible -- there are often obvious data recording errors in actual analysis, although most of these have been eliminated from the Ramanathan datasets. Use "Data/Select all" then "DatalDisplay values" to list all of the datapoints. Scan through the listing to see whether the data stay within the expected range (I expected the range to be about 2.0 to 4.0 max), whether there are any obvious errors, and whether there are any surprises (high hsgpa with low colgpa or, less likely, low hsgpa with high colgpa 2 ).What is your overall impression about whether for the same student high school grade points are greater than college grade points or vice versa?
