Member Function Documentation

cxsc::real subpavings::RealKDEMidEstimator::operator()

(

const std::vector< cxsc::real > &

x

)

const [virtual]

Evaluate the kernel density estimate at single point.

Parameters:

x	the point at which to evaluate the kernel density, given as a vector of reals rather than an rvector.

Returns:

the real kernel density estimate evaluated at the rvector corresponding to x.

Implements subpavings::RealPointwiseFunctionEstimator.

  {
    return fobj.kde(x);
  }

cxsc::real subpavings::RealKDEMidEstimator::operator()

(

const cxsc::rvector &

x

)

const [virtual]

Evaluate the kernel density estimate at single point.

Parameters:

x	the point at which to evaluate the kernel density.

Returns:

the real kernel density estimate evaluated at x.

Implements subpavings::RealPointwiseFunctionEstimator.

  {
    return fobj.kde(x);
  }

cxsc::real subpavings::RealKDEMidEstimator::operator()

(

const cxsc::ivector &

x

)

const [virtual]

Estimate of the function value over a box x.

Parameters:

x	the box over which to estimate the kernel density.

Returns:

the real kernel density estimate evaluated at the mid-point of x.

Implements subpavings::RealPointwiseFunctionEstimator.

  {
    int lb = Lb(x);
    int dim = lb + Ub(x) + 1;
    std::vector < cxsc::real > rv(dim);
    for (int i = 0; i < dim; ++i) rv[i] = mid(x[lb+i]); 
    return fobj.kde(rv);
      
  }

cxsc::real subpavings::RealKDEMidEstimator::visit

(

SPnode *

spn

)

const [virtual]

The visit operation.

Parameters:

spn	a pointer to an SPnode to be visited.

Returns:

the real kernel density estimate evaluated at the midpoint of the box associated with the node pointed to by spn.

Implements subpavings::SPValueVisitor< cxsc::real >.
