Document Summary
Student number: there are 20 pages including this page, the last page is a table of formulae that may be useful. 1: (5 marks) for each of the following models state whether its parameters can be esti- mated using standard linear regression techniques. If linear regression can be used, what are the independent and dependent variables that should be used if using proc reg in sas? (a) yi = 0 + e 1xi + i. Independent variable: xi. (c) yi = 0 + 1xi1 + 2xi2 + i where 2 is known to be 5. Independent variable: xi1: (5 marks) a simple linear regression equation was t to 10 observations. Complete the analysis of variance table with the column headings: source of variation, Degrees of freedom, sum of squares, mean square, f ratio, and p-value. i=1(xi x)(yi y ) = 50, p10 were calculated: p10 i=1(yi y )2 = 100, r2.
