In addition to what Mike and Andy have said, see Frank Harrell's post in this thread on the R help list:

Harrell is the author of the well-known book, Regression Modeling Strategies.  You can probably find other comments he has made in the Google Groups Medstats group, or on StackExchange / Cross Validated.

Hi everyone,

 I am working on my dissertation and will be doing a multivariate logistical
 regression for my analysis.
 I have continuous co-variates and a dichotomous dependent variable.
 I came across the following reference:
 Moons, E., Aerts, M., & Wets, G. A tree based lack of fit test for multiple
 logistic regression.   The authors compare Tree based lack of fit to
Hosmer and Lemeshow.
 Is this an accepted alternative to H & L?  I would appreciate any thoughts
 the you all may have.

Thank you so much
