Estimated Hazard Rate Object


Description

This class of objects is returned by muhaz, which estimates the hazard function from censored data.

Arguments

pin.common

list containing the input parameters. Its components are: * times - the survival times vector * delta - the censoring vector * nobs - the number of observations * min.time - the minimum time used in analysis * max.time - the maximum time used in analysis * n.min.grid - number of points in the minimization grid * min.grid - the minimization grid * n.est.grid - number of points in the estimation grid * bw.pilot - the pilot bandwidth * bw.smooth - the smoothing bandwidth for the local optimal bandwidths * bw.method - the method used to estimate the hazard rates * b.cor - boundary correction used * kernel.type - kernel function used in the smoothing

est.grid

the estimation grid where the hazard rates are computed.

haz.est

the hazard estimates calculated at the estimation grid points.

imse.opt

IMSE for the optimal bandwidth.

bw.glob

optimal global bandwidth. For bw.method="global" only.

glob.imse

vector of IMSE, computed at each point in bw.grid. For bw.method="global" only.

bw.grid

Grid of bandwidth values used in the minimization. For bw.method="global" or "local".

bw.loc

vector of optimal local bandwidths computed by minimizing the MSE at each point in the minimization grid. Not used for bw.method="local".

bw.loc.sm

vector of smoothed local bandwidths, computed at each point in the estimation grid by smoothing bw.loc using bw.smooth as the smoothing bandwidth. Not used for bw.method="global".

bias.min

vector of minimized bias, computed at each point in the minimization grid for the optimal local bandwidth. For bw.method="local" only.

var.min

vector of minimized variance, computed at each point in the minimization grid for the optimal local bandwidth. For bw.method="local" only.

k.grid

grid of nearest neighbor numbers used in the minimization. For bw.method="knn" only.

k.imse

vector of IMSE, computed at each of the points of k.grid. For bw.method="knn" only.

k.opt

optimum number of nearest neighbors. For bw.method="knn" only.

METHODS
