In order to estimate efforts for a WEB software project we need to use a software cost estimation model. I want to know whether we do have methods in place to check the effectiveness and reliability for checking the WEB software cost estimation models.
I cam across a very simple cost estimation template for web projects. http://www.divageekdesigns.com/2012/03/27/how-to-estimate-time-for-new-web-projects-accurately/
respected sir, Mr. Muthu Ramachandran
Thanks a lot for your suggestion it is very helpful

please check out my paper for modern software evaluation
"Survey and evaluation of agent oriented software engineering."
It's very encouraging to see that you are considering *actually* using an effort estimation model for your web projects.
What would be best is if you have access to some of your own historical data. If this is the case you can retrospectively apply the models and then compare predicted with actual to determine the residuals (differences). Depending upon your goal you might wish to minimise mean error so use mean absolute residual or if you're risk averse you might consider sum of the squares of the residuals
If you have sufficient data you could also see if any of the models benefit from local calibration (but I suggest you split the data into training and validation sets in order to avoid over fitting).
In terms of finding estimation models, I agree with Maya, that you should look at some of the work of Emilia Mendes and her co-workers.
