• rmm(), rm_bin_summary(), and nonlinear_bins(): Updated the documentation for the threshold arguments along with the divisor arguments. These were updated along with the Details section of the nonlinear_bins() function documentation to provide a better explanation of the binning algorithm under the hood.
• probability_of_survival(): Updated the Return section documentation to be more accurate that the output is not a percentage, it is the predicted probability of survival on a scale from 0 to 1. A previous version of this function was multiplied by 100 to seem more like a percentage.
