How to find nothing 2.0

Abstract:
Various problematic statistical approaches can be used in regression analyses to help find no significant relationship between explanatory variables and response variables-"to find nothing." In an earlier paper, I provided examples of finding nothing from firearm studies, focusing on the lack of statistical power. In this Viewpoint, I offer three examples of "finding nothing" from firearms research and focus on a single hypothesis-that household gun ownership levels affect suicide rates, examining one type of evidence-cross-sectional ecological studies. I discuss studies examining variations in suicide rates across US states, US cities, and nations, highlighting the work of the one firearm researcher who continually "finds nothing."

According to the range rule of thumb, any value above or below two standard deviations, 2σ from the mean, μ is considered unusual.

Detection of Black Holes
Their closest cousins are neutron stars, which are composed almost entirely of neutrons packed against each other, making them extremely dense. A neutron star has the same mass as the Sun but its diameter is only a few kilometers. Therefore, the escape velocity from their surface is close to the speed of light.
Not until the 1960s, when the first neutron...
