Refer to the Prostate cancer data set in Appendix C.5 and Case Study 16.49. Carr " one-way analysis of covariance of this data set, where the response of interest is PS out a (variable 2), the single factor is Gleason score (variable 9), and the possible covariates level cancer volume (variable 3) and weight (variable 4), The analysis should consider transfers ions of the response variable and the covariates. Document step~ taken in your analysis and justify your cone conclusions.
Case Study 16.49
Refer to the Prostate cancer data set in Appendix C.5. Carry out a one-way analysis of variance of this data set, where the response of interest is PSA level (variable 2) and the single factor is Gleason score (variable 9). The analysis should consider transformations of the response variable. Document steps taken in your analysis, and justify your conclusions.
