Hello I really need some help. Here are my assignment instructions.

Perform a Multiple Regression Analysis paralleling the HBAT analysis performed in the textbook and in class, but now use the HATCO dataset (see HATCO_X1-X14_Tabs data file).

Include the following analyses:

- Consider the overall general Model X9 = X1 X2 X3 X4 X5 X6 X7
- Perform a Correlation Analysis
- Fit and Analyze the best single independent (simple) regression analysis
- Perform a Stepwise Regression Analysis to select the best subset model using Alpha = 0.05
- Perform a Full Model (Confirmatory) Regression Analysis using Alpha = 0.05
- Using the best subset from the Stepwise Regression Analysis now include variable X8 (Firm Size) and analyze its effect and the new resultant model
- Analyze and Discuss the Multiple Regression Analysis Assumptions, e.g., Linearity, Normality, Homoscedasticity, and Independence using Residual and other Graphical/Statistical measures and tests for all Model Analyses
- Similarly Analyze and Discuss any Influential observations with recommendations, as well as the Model’s Multicollinearity.

Here is what I've done so far for my code:

FILENAME REFFILE "/home/tmaciver7840/my_content/HATCO X1-X14.txt" TERMSTR=CR;

PROC IMPORT DATAFILE=REFFILE

DBMS=tab

OUT=WORK.IMPORT;

GETNAMES=YES;

RUN;

PROC CONTENTS DATA=WORK.IMPORT; RUN;

Input ID X1 X2 X3 X4 X5 X6 X7 X8 X9 X10 X11 X12 X13 X14;

Data WORK.IMPORT;

Set WORK.IMPORT (Keep = ID X1 X2 X3 X4 X5 X6 X7 X9);

Label ID = 'ID - Identification Number'

X1 = 'X1'

X2 = 'X2'

X3 = 'X3'

X4 = 'X4'

X5 = 'X5'

X6 = 'X6'

X7 = 'X7'

X8 = 'X8'

X9 = 'X9'

X10 = 'X10'

X11 = 'X11'

X12 = 'X12'

X13 = 'X13'

X14 = 'X14';

Proc Print Data = WORK.IMPORT;

*;

*;

* Correlation Matrix - All Variables;

*;

Proc Corr Data = WORK.IMPORT;

Var X1 X2 X3 X4 X5 X6 X7 X9;

Plot NQQ.*R. NPP.*R.; * NQQ.*R and NPP.*R request specific separate

Normal Quantile and Normal Probability Plots;

*;

How do I perform the rest of the regression analyses? I really appreciate any help! (Attached is the dataset)

This is not the right forum for this question. You should try a more appropriate forum.

Under Analytics there is SAS Statistical Procedures.
