## Distance to the Large Magellanic Cloud

### Description

This dataset is a collection of 25 measurements of the distance to the Large Magellanic Cloud (LMC), the largest galaxy now orbiting the Milky Way Galaxy (Clementini 2003). The measurements are made by different research groups using different methods: Cepheid and RR Lyrae luminosities, red clump giants, Supernova 1987a expansion, and so forth. Each distance modulus (DM) measurement is accompanied by its standard deviation. The dataset is discussed at http://astrostatistics.psu.edu/datasets/LMC_distance.html. This dataset is useful for statistical methods treating heteroscedastic measurement errors.
