WHENWhen validating duration inputs in survival analysis
ACTIONReject negative or zero durations with ValueError
CONSEQUENCENegative durations are mathematically invalid in survival analysis, causing incorrect hazard rate calculations and producing meaningless survival curves that misrepresent actual time-to-event distributions
WHENWhen processing event_observed array for survival models
ACTIONCast event_observed to integer type and then to boolean
CONSEQUENCEInvalid event values (non-0/1, non-boolean) will produce undefined behavior in likelihood calculations, potentially causing silent errors in survival function estimation
WHENWhen accepting user-provided DataFrame in fit() method
ACTIONCreate a shallow copy of the input DataFrame before extraction operations
CONSEQUENCEThe original DataFrame will be permanently modified by .pop() operations on duration/event/weights columns, corrupting user data and violating data isolation principles
