    "abstract": "We perform an objective change-point analysis on 106 years of historical\nhurricane number data. The algorithm we use looks at all possible combinations\nof change-points and compares them in terms of the variances of the differences\nbetween real and modelled numbers. Overfitting is avoided by using\ncross-validation. We identify four change-points, and show that the presence of\ntemporal structure in the hurricane number time series is highly statistically\nsignificant.",
