JRC statistical audit of the Mobile Connectivity Index

cover
This technical report summarizes the statistical audit of the Mobile Connectivity Index (MCI). The MCI is thoroughly considered by experts in the GSM Association. The methodology of the MCI is coherent and follows well the OECD-JRC (2008) recommendations for constructors of composite indicators. We found that the unification of the normalisation procedure for all indicators may enhance the reliability of the index. Further refinement of the MCI indicator set, which has been already on the agenda of the GSMA and the planned replacement of proxies by better indicators can later surely help to improve the statistical qualities of the MCI in the future, once data availability allows it. The overall implications of the uncertainty analysis are that the uncertainty in the rankings is manageable, and allows meaningful conclusions to be drawn from the index. As recommended frequently by the JRC team in its statistical audits, it would be worthwhile to publish confidence intervals alongside the index scores and rankings in case of the MCI.
