I have a statistical question that I hope someone can answer.

I am doing a research about relationship between satisfaction and loyalty. Each variable had 5 dimensions that were measured (5 dimensions determining loyalty and 5 determining satisfaction).

I did multiple regression via SPSS, but 4 out of 5 dimensions are shown not to be significant. I really think all of the dimensions are important for my research and I don't want to drop them out of the model.

Is it possible to leave them all as they are, and then do simple regression for overall loyalty and satisfaction?

Thanx in advance,

Iva
