Calculation of the contant term in the AMISE plugin bandwidth rule PlugInBand.
NP.M.Estimate(xin, cens, xout)A vector of data points
The point at which the estimates should be calculated.
Censoring Indicators.
A scalar with the value of the constant.
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).
