Constructor & Destructor Documentation

rdGCVSplineSet::rdGCVSplineSet (  const char *  aFileName  )

Construct a set of generalized cross-validated splines from file. Parameters: aFileName  Name of the file.

rdGCVSplineSet::rdGCVSplineSet (  int  aDegree, rdStorage *  aStore, double  aErrorVariance = 0.0 )

Construct a set of generalized cross-validated splines based on the states stored in an rdStorage object. Each column in the rdStorage object is fit with a spline of the specified degree and is named the name of its corresponding column label. Note that column labels in the storage object are assumed to be tab delimited. Parameters: aDegree  Degree of the constructed splines (1, 3, 5, or 7). aStore  Storage object. aErrorVariance  Estimate of the variance of the error in the data to be fit. If negative, the variance will be estimated. If 0.0, the fit will try to fit the data points exactly- no smoothing. If positive, the fits will be smoothed according to the specified variance. The larger the error veriance, the more the smoothing. Note that this is the error variance assumed for each column in the rdStorage. If different variances should be set for the various columns, you will need to construct each rdGCVSpline individually. See also: rdStorage rdGCVSpline

Member Function Documentation

void rdGCVSplineSet::construct (  int  aDegree, rdStorage *  aStore, double  aErrorVariance )  [private]

Construct a set of generalized cross-validated splines based on the states stored in an rdStorage object. Parameters: aDegree  Degree of the constructed splines (1, 3, 5, or 7). aStore  Storage object. aErrorVariance  Error variance for the data.

rdStorage * rdGCVSplineSet::constructStorage (  int  aDerivOrder, double  aDX = -1 )

Construct a storage object (see rdStorage) for this spline \ or for some derivative of this spline set. Parameters: aDerivOrder  Derivative order. 0 constructs from the spline, 1 constructs from the first derivative of the spline, 2 constructs from the second derivative of the spline, etc. aDX  Spacing of the data points in the independent variable. If negative the spacing of the independent variable is taken from the original data, as determined from the first non-NULL spline in the set. aDX has a default value of -1. Returns: Storage object. If a valid storage object cannot be constructed NULL is returned. See also: rdStorage

rdGCVSpline * rdGCVSplineSet::getGCVSpline (  int  aIndex  )

Get the function at a specified index. Parameters: aIndex  Index of the desired function: 0 <= aIndex < getFirstEmpty(). Returns: Function at index aIndex. If aIndex is not value NULL is returned.
