GLM output

I am conducting a series of GLMs in order to find the minimum adequate model, the largest model in which all factors are significant. In some of my models all factors are significant, except for the intercept... what does this mean??

thanks

cool thanks... so if i were to plot each of the significant terms from the GLM output then the intercept would have to be included for each one?

ie... the intercept is 0.25;
- factor x has coefficient of 0.5, thus a line of y=0.5x + 0.25
- interacting factor x*z has a coefficient of 0.4, thus a curve of y=0.4(x^2) + 0.25
- a further interacting factor x*z*a has a coeff. of 0.1; thus a curve of y=0.1(x^3) + 0.25


does that seem to make sense?

thanks
