Help in statistics

do mathematic questions in order for me to check my work. Example questions are seen below. Please only quote if you are a competent degree educated in mathematics example of question The ‘Q6a’ tab in the Excel spreadsheet provides the summary statistics of 84 regressions based on cross-sectional data for each month between January 2001 and December 2007. The following summary statistics are shown in the spreadsheet: • multiple R • R-square • adjusted R-square • standard error • significance of F. Define each of the above terms and interpret each of the statistics in regards to the data over the time period from January 2001 to December 2007. (5 marks) (b) (i) Consider the following notations: Ri = return of stock i for a particular month Xi1 = exposure of stock i to the constant unit of 1 Xi2 = exposure of stock i to the size Xi3 = exposure of stock i to the momentum Xi4 = exposure of stock i to the value f1 = the intercept term f2 = the regression coefficient of size f3 = the regression coefficient of momentum f4 = the regression coefficient of value. Complete the formula for the specific returns (or residual term) of stock i for a particular month, Ui, given the information above and the linear regression model. What do the specific returns attempt to measure? (2 marks) (ii) Calculate the monthly specific returns (i.e. the residuals of the regressions) for CBA, WES and BHP for the 84-month in-sample period. To do this calculation, use the formula derived from part (i), the data given in the notations in part (i), and the data in the ‘Q6b’ tab of the Excel spreadsheet. From your Excel results, paste a copy of the specific returns for CBA, WES and BHP for the months of January 2001 and December 2007 only in the Word document of your assignment (and in the format below).
