[Tiago Pereira]

Thank you so much for your time and willingness to help us, Clyde.

[River Huang]

I can not appreciate more for your helpful suggestions, Clyde.

[Clyde Schechter]

Thanks to all of you for your kind thoughts.

Greater thanks are due to those others on Statalist (including the earlier listserve version) from whom I learned so much. It is because of them that I have knowledge to share. I don't mention them by name because they are numerous, and I would undoubtedly slight some by inadvertently leaving them out. In the end, I am just passing forward what I have learned from others, and perhaps adding a bit of my own experience.

Thanks to you all.

Schechter's posts are treasure troves of useful information. Often times, I find clearer and more comprehensive explanations in his posts than in the methodological literature. Please keep up the good work, and know that many people who rarely comment find what you're doing very useful.
