The time variation of the fine structure constant: A statistical analysis of astronomical data

Mostrar todas las versiones(3)

Aims. We analyze different data of the variation of the fine structure constant obtained with different methods to check their consistency.Methods. We test consistency using the modified student test and confidence intervals. We split the data sets into smaller intervals. A criterion for this select...
