What kind of statistical method do you need? What is the data about? It is very seldom that people or companies specialise in all statistical methods.

Thank you, Roman,

I solved the problem.

Are you saying you are a statistician? This is in case I need help again. I usually run my data on SPSS. I just needed a second person to run the data for a second time.

But thank you, really.

Dear Yvette, I thought that maybe you are looking for some specific methods such as SEM, PCA, etc. But If you already managed to solve the problem, I wish you good luck with the research. R.
