NP.M.Estimate {NPHazardRate}

Estimate of bandwidth constant

Description

Calculation of the contant term in the AMISE plugin bandwidth rule PlugInBand.

Usage

NP.M.Estimate(xin, cens, xout) 

Arguments

xin

A vector of data points

xout

The point at which the estimates should be calculated.

cens

Censoring Indicators.

Details

Approximates the term

M = \int_0^T \frac{ \lambda_T(x) }{1-F(x)} \,dx

which is needed in the optimal AMISE bandwidth expression of PlugInBand. The integrand

\frac{\lambda_T(x)}{1-F(x)}\,dx

is calculated by HRSurv and integration is performed via the extended Simpson's numerical integration rule (SimpsonInt).

Value

A scalar with the value of the constant.
