Estimate is maximum-likelihood estimate, SE is the standard error of the estimate, 2.5% and 97.5% indicates the lower and upper bounds of a 95% confidence interval around the estimate. Parameter a is the y-intercept of Line 1, parameter b is the slope of Line 1, parameter c is the slope of Line 2, parameter d is the breakpoint separating Line 1 and 2.
