faraways "practical regression" is a helpful ressource on regression and regression diagnostics. http://cran.r-project.org/doc/contrib/Faraway-PRA.pdf

Dear Farideh,

See the attached file, for preliminary interpratation.. for more detailed, I shall provide you more files. Keep me updated.

Take a look here, it is written in R:

And another better example here:

Dear Farideh,

Your plots perform residual analysis and diagnostics for regression.

But for diagnostics of logistic regeression those plots are not quite appropriate (more hard to interpret).

Diagnostics and model checking for logistic regression for practical use:

Note, that interpretation of the parameters and regression diagnostics are different things.

For plotting the estimated effects in the model, try the effects package.

library(effects)

plot(allEffects(yourmodel))

For effects plot, you can see here, nice interpretation
