 abstract = {The intent of this paper is to present an alternative estimator to measure the accuracy
of the polls and some derived estimators, which seeks to cushion problems detected in
the available options. This is achieved by adjusting the value of the absolute differences
according to the statistical error of the estimates and, to allow a symmetrical behavior
of the indicator, to convert it into its logarithm. The expectation is that these estimators
provide a useful tool for future analysis on the accuracy of pre-election polls.},
