Hello everyone. I'm new to this forum. I've been googling all morning long trying to find a blueprint or model for my Business Analysis project. Minitab is something I am not familiar with. I haven't had stats in six years, and the course was relatively easy back then. But this is one of my last four classes and I have to make at least a B. The requirements: overview of study; statistical discussion; model building; miscellaneous. Model building techniques include: forward selection, backward elimination, stepwise, best subsets regression. Model selection criteria: coefficient of variation, MSE, S, C-P. All graphs and Minitab or SPSS output are to be placed at the end of the paper, and referred to as figure 1, figure 2, etc. Does anyone have any suggestions as far as links, websites, resources, etc.?

you should do the following

1) relax ..there is still time

2) search wikipedia for definitions of regression (it basically explains a dependent variable say sales with an equation based on independent variables like gdp growth in an economy, number of people in the economy etc. y= a+ bx1+cx2+... is an regression equation where x1,x2, ..xn are independent variables......

when you create a model, you try and take as many variables on the right side and fit an equation on the test sample.......say i know values of y ,x1,x2, for 100 values . i will divide the data into training and validation in ratio 60:40.

then fit an equation using spss regression /analyze , or using excel (using analysis toolpak vba add -in)

then i will take that equation and test it on remaining 40 values to see actual versus predicted value and try and minimize error , or maximize r square.

3) stepwise selection- forward selection , put the variable with maximum co relation , then add one more , then add one more to get optimum variables

backward selection...take all variables then reduce one and do above steps and then do above steps

4) google search for "regression models in spss" some examples will have datasets also..

5) take textbook of stats ,pick up your course and read chapter on regression

6) all the best and hopefully you will get an A

7) websites are
