Survival probability conditional on the observed data estimation for interval censored data
ICsur(L, R, M, t, method, dist)The numericvector of left limit of observed time. For left censored observations L == 0.
The numericvector of right limit of observed time. For right censored observation R == inf.
The numeric vector of marker value.
A scaler time point used to calculate the the ROC curve
A character indication type of modeling. This include nonparametric "np",parmetric "pa" and semiparametric "sp".
A character incating the type of distribution for parametric model. This includes are "exponential", "weibull", "gamma", "lnorm", "loglogistic" and "generalgamma".
Return a vectors:
positive P(T<t|L,R,M).
negative P(T>t|L,R,M).
