Regression on Binned data

Hi,

Can I carry out linear regression reliably with binned data. IE. data on cases falling into a series of ranges over time.

I can imagine that if the upper bin limit is used to describe the data that an ordinary regression will proabably still estimate the slope, but overestimate the intercept.

Are there any methods for this type of data (small example below)

Year Bin
2002 1
2002 1
2002 2
2003 1
2003 2
2003 3
2003 3
2003 3
2004 1
2004 3

Regards

AC
