The table given above consisting of one dependent (Total score of projects) and eight independent variables (work effort, ufp rating, whether more than one computer is used, elapsed time, effort test, function points, average team age and defects delivered). For the given dataset answer the following questions (for =0,10): (PLEASE USE MINITAB)
state your study steps while you are solving questions in minitab. For Example STAT-REGRESSION-FIT REGRESSION - .... -
- Please estimate the total score of projects by using a single independent variable. Please explain the criteria you use to determine the best independent variable.
- Interpret your results.
- Construct the ANOVA table for the simple linear regression model.
- Test the significance of the simple linear regression model
- Estimate the ^2 of your simple linear model
- Calculate R^2 of your simple linear model and interpret your result
- Test lack of fit of your simple linear model
MULTIPLE LINEAR REGRESSION PART ( Now use all independent variables (for =0,10) )
- Estimate the parameters of the multiple regression model
- Construct the ANOVA table
- Test the significance of the model
- Calculate R^2 of your model
- Check the multicollinearity
- Check the model adequacies
