| void CalibrationDataEigenVariations::excludeNamedUncertainty |
( |
const std::string & |
name |
) |
|
exclude the source of uncertainty indicated by name from eigenvector calculations
| TMatrixDSym CalibrationDataEigenVariations::getEigenCovarianceMatrix |
( |
|
) |
const |
also provide (some) access to the underlying information: covariance matrix corresponding to eigenvector variations
| TMatrixDSym CalibrationDataEigenVariations::getEigenCovarianceMatrixFromVariations |
( |
|
) |
const |
covariance matrix corresponding to eigenvector variations constructed from the eigen-variation
| bool CalibrationDataEigenVariations::getEigenvectorVariation |
( |
unsigned int |
variation, |
|
|
TH1 *& |
up, |
|
|
TH1 *& |
down | |
|
) |
| | const |
obtain the "up" and "down" variations for the given eigenvector number. The return value will be false if the eigenvector number is invalid.
| TMatrixD CalibrationDataEigenVariations::getJacobianReductionMatrix |
( |
|
) |
const |
matrix to remove unecessary rows and columns from covariance
| bool CalibrationDataEigenVariations::getNamedVariation |
( |
unsigned int |
nameIndex, |
|
|
TH1 *& |
up, |
|
|
TH1 *& |
down | |
|
) |
| | const |
obtain the "up" and "down" variations for the source uncertainty pointed to by the given index (which is assumed to correspond to the value retrieved using getNamedVariationIndex()). The return value will be false if the index is out of bounds.
| bool Analysis::CalibrationDataEigenVariations::getNamedVariation |
( |
const std::string & |
name, |
|
|
TH1 *& |
up, |
|
|
TH1 *& |
down | |
|
) |
| | const |
obtain the "up" and "down" variations for the named uncertainty. The return value will be false if the given name is not listed as being excluded from the eigenvector calculations.
| unsigned int CalibrationDataEigenVariations::getNamedVariationIndex |
( |
const std::string & |
name |
) |
const |
retrieve the integer index corresponding to the named variation. This can be used to speed up computations by avoiding string comparisons. Note that this function is not protected against passing an invalid name.
| unsigned int CalibrationDataEigenVariations::getNumberOfEigenVariations |
( |
|
) |
const |
retrieve the number of eigenvector variations
| unsigned int CalibrationDataEigenVariations::getNumberOfNamedVariations |
( |
|
) |
const |
retrieve the number of named variations
| void CalibrationDataEigenVariations::initialize |
( |
double |
min_variance = 1.0E-20 |
) |
|
carry out the eigenvector computations. Exclusion of any source of uncertainty has to be done before calling this method
| bool CalibrationDataEigenVariations::isExtrapolationVariation |
( |
unsigned int |
nameIndex |
) |
const |
flag whether the given index corresponds to an extrapolation variation
| vector< string > CalibrationDataEigenVariations::listNamedVariations |
( |
|
) |
const |
list the named variations
| void CalibrationDataEigenVariations::mergeVariations |
( |
const IndexSuperSet & |
set |
) |
|
merge all variations in any of the given sets
| void CalibrationDataEigenVariations::mergeVariations |
( |
const IndexSet & |
set |
) |
|
merge all variations in the given set
| void CalibrationDataEigenVariations::mergeVariationsFrom |
( |
const size_t & |
index |
) |
|
merge all variations starting from the given index
| void CalibrationDataEigenVariations::removeVariations |
( |
const IndexSuperSet & |
set |
) |
|
remove all variations in any of the given sets
| void CalibrationDataEigenVariations::removeVariations |
( |
const IndexSet & |
set |
) |
|
remove all variations in the given set
