Overload List
| Evaluate | Evaluates the natural logarithm of the fitted density at a point. |
| Evaluate | Evaluates natural log-density at a collection of query points. |
EvaluateLog(Double)
Evaluates the natural logarithm of the fitted density at a point.
public double EvaluateLog(
double value
)Parameters
- value Double
- The query coordinate, in observation units.
Return Value
DoubleThe natural log-density. NaN propagates. Either infinity and zero density return negative infinity. Signed custom kernels have an undefined logarithm and may return NaN.
Remarks
Uses log-sum-exp and analytic logarithms for built-in kernels. Custom kernels may provide
a logarithmic delegate to preserve values after their ordinary density function underflows.
EvaluateLog(Vector<Double>)
Evaluates natural log-density at a collection of query points.
public Vector<double> EvaluateLog(
Vector<double> values
)Parameters
Return Value
Vector<Double>A new caller-owned vector preserving query order and labels, with the point semantics of EvaluateLog(Double).
Exceptions
