回复 第6楼 的 summerbaihu： I refuse to answer any questions on whether the use of any software is correct when I have no clue about whether the people using the software is competent in doing the analysis and/or interpreting the results.
I don't like "user-friendly" statistical software that is too friendly to people that should not use the software. It is sufficient to be friendly to statisticians, but not to others. It's like sweet wine --- you have to be old enough before you should try it, even though kids like that sweetness.
