My experience with AMSTAT consulting was brief but sweet because I had my dissertation quite written, but I needed some final touches and guidance on the analysis to reach final approval. I carried out my study on leadership and a series of variables in the workplace (commitment, commitment, satisfaction, etc.) and although I started with a fairly simple method plan, my study evolved in some way with the guidance of my very ambitious president to the point where I needed to use SEM to direct my RQs.
