Aside from the visual funnel plot, statistical techniques for detecting publication bias have also been proposed. They're controversial as they typically have lower electricity for detection of bias, and also could make Fake positives less than some conditions. For example modest study consequences (biased smaller scientific studies), wherein methodological variations concerning lesser and larger scientific studies exist, may trigger asymmetry in impact measurements that resembles publication bias.
A funnel plot expected without the file drawer problem. The most important research converge on the suggestion even though lesser studies demonstrate more or less symmetrical scatter at the base
