Logistic regression coefficients showing that age class categories in years predicted the probability that a male was a raider.

The probability values show whether the coefficients were significantly different from zero for each age class.1Age class 10–14 years was used as a baseline age class and as result its' coefficient is set to zero. We used data for the all males over 10 years of age from Amboseli National Park (n = 365 elephants). The total number of males in each age class is indicated and the number of crop raiders in each age class is shown in parenthesis. The odds ratio is the exponent of the coefficient and provides a measure of how more likely a male from a named age class is to be a raider compared to the raiding status of the baseline age class.
