A cancer specialist from the Los Angeles County General Hospital (LACGH) rated patient optimism in 20 to 40 year old patients with incurable cancer in 1970. In 1990, the researcher examined hospital records to gather the variables below. Use Multiple Regression Analysis to answer the questions below. Include all SPSS output at the end of your document in an appendix section.

a. Do the IVs correlate significantly and/or practically with the DV?

b. Is multicollinearity a concern among the IVs?

c. Interpret the R, R2, and Adjusted R2 for all IVs entered simultaneously. Do they change when using a Stepwise approach? Explain.

d. What variables provide a significant unique contribution to the model when using a standard multiple regression? Interpret their significance, b and Beta weights, squared semi partial correlations, and structure coefficients. Are these findings supported when using a Stepwise approach?
