Hi,
In my recent research, I generate one dataset (Call it T) which is combined
by 3 small datasets. The three datasets are generated by the folowed linear
models with 200 times:
A y = 200 + 20 x + e
B y = 120 + 10 x + e
C y = 100 - 5x + e
where y is dependant variable, x is indendent variable with a uniform
distribution defined in the interval 0 to 10 and e is the error with normal
distribution. After I finished the research, I wondered that whether we can
know how many datasets make up Dataset T if we do not know this fact in
advance. In other words, is there any method that can identify different
groupt of observations that has some particular characters? Can anybody give
me some advice?
Thanks a lot.
David
