Detailed Description

Class representing a time point in a kaplan-meier estimator

Constructor & Destructor Documentation

◆ TimePoint() [1/2]

theplu::yat::statistics::KaplanMeier::TimePoint::TimePoint ( void )

Default constructor

◆ TimePoint() [2/2]

theplu::yat::statistics::KaplanMeier::TimePoint::TimePoint	(	unsigned int	event,
		unsigned int	censored
	)

Parameters

event	number of events occuring at this time point
censored	number of data points being censored at this time point.

Member Function Documentation

◆ at_risk()

unsigned int theplu::yat::statistics::KaplanMeier::TimePoint::at_risk ( void ) const

Number of subjects being at risk at this point in time, i.e., number of data points that occur or are being censored at this time point or later.

◆ censored()

unsigned int theplu::yat::statistics::KaplanMeier::TimePoint::censored ( void ) const

Number of data points being censored at this time point

◆ event()

unsigned int theplu::yat::statistics::KaplanMeier::TimePoint::event ( void ) const

Number of events occurring

◆ survival_proportion()

double theplu::yat::statistics::KaplanMeier::TimePoint::survival_proportion ( void ) const

Returns: an estimate of proportions of samples alive.

The proportion is estimated as $s(t) \prod_{i:t_i\le t} \left( 1 - \frac{x_i}{n_i} \right)$ , where $d_i$ is number of events at time $t_i$ and $ n_i $ is subjects at risk at time $ t_i$ (see at_risk()).
