[BlindMath] Mediation analysis, structure equation modelling, and amos.

[faiz rasool]

Dr. Jonathan,

Are you aware of any  tutorial that I can read and  perform structure
equation model on the data.

My concern is that I need the results of SEM in my dissertation,  and
I am not so sure, how I can copy  output generated by R to my thesis.
Plus, I have very little experience of using R, so, if I can locate a
set of command that I can quickly follow to get data into R, perform
SEM, and  move the results to Microsoft word,  it will be perfect, and
this will ease my troubles with SPSS

Regard's,
Faiz.
