Comparison of TCP Throughput with Digital Access Index
DAI indicates - Avalibility of Infrastructure - Affordibility of access - Education Level - Quality of ICT services - Internet Usage
Since the PingER Derived Throughput is linearly proportional to RTT, countries close to the U.S. (i.e. the U.S., Canada and Mexico) may be expected to have elevated Derived Throughputs compared to their DAI. We thus do not use the U.S. and Canada and Mexico in the correlation fit.
