Just how badly biased is your pre-election survey? Once the election results are in, our scalar measures *B* and *B_w* provide convenient, single number summaries. Our *surveybias* add-on for Stata will calculate these and other measures from either raw data or from published margins. Its latest iteration (version 1.4) has just appeared on SSC. Surveybias 1.4 improves on the previous version by ditching the last remnants of the old numerical approximation code for calculating standard errors and is hence much faster in many applications. Install it now from within Stata by typing

`ssc install surveybias`
