The Correlation Question


Explanation of the colors:

in the range of one sigma
in the range of two sigma
in the range of three sigma
outside of the range of three sigma

During the last century many correlation constants are proposed to correlate the ancient Maya calendar and the Christian calendar. Chronological data from different sources leads to different expectations independent of a correlation. The internal accuracy for each expectation is given below, and the reliability of the sources and their chronological interpretations are discussed in Wells, Fuls (2000). The expectations are tested for various correlations as seen in the following table. The background colors are indicating how the data and the correlation fit to the expectation.
