متن کاملDifferences between Antarctic and non-Antarctic meteorites: An assessment
The discovery of a statistically significant number of meteorites in Antarctica over the past 20 years has posed many questions. One of the most intriguing suggestions that came up during the study of the Antarctic samples was that there might be a difference between the parent populations of Antarctic and non-Antarctic meteorites. This interpretation was put forward after the detection of a si...

We construct a measure of overvaluation us...
