Abstract: A method and device may estimate the accuracy of position data using kernel density estimator. The method may include receiving, from a plurality of user devices, network requests having embedded position data representing locations of the plurality of user devices. The method further includes extracting, from the network requests over a time period, the embedded position data of a user device associated with the plurality of user devices; and receiving baseline position data representing the locations of the user device over the time period. The method included generating a probability density estimate of the locations of the user device based on a kernel density estimator using the baseline position data, determining accuracy scores for the embedded position data using the probability density estimate of the locations, and filtering the embedded position data to remove outliers from the embedded position data.
