SegSeriesTrajectories-class: Class '"SegSeriesTrajectories"'

In deltaGseg: deltaGseg

Description

Objects of this class is a product of the clusterSegments function.

Objects from the Class

Objects can be created by calls of the form new("SegSeriesTrajectories", ...).

Slots

ssmatrix:

Object of class "data.frame" The output is a data.frame with the following information (in columns): the observed data ("observed"), the estimated, wavelet denoised data ("estimated"), the residuals of the estimation ("residuals"), the estimated subpopulations IDs ("subpopulations"), the series IDs/filenames ("seriesID")

ssparams:

Object of class "character" Parameters used to run the clustering algorithm, clusterSegments.

sparams:

Object of class "character" Parameters used to run the segmentation algorithm, denoiseSegments.

smatrix:

Object of class "matrix" A matrix containing the preliminary results from segmentation/denoising for each (sub)series generated by transformSeries. Each list element contains the following information in matrix form (in columns): the observed data (1st column), the estimated, wavelet denoised data (2nd column), the residuals of the estimation (3rd column), the starting/ending time points of each segment (4th/5th columns), the estimated segment IDs (6th column), the quantiles of the estimated data [minimum, 5%, 10%, 15%, ..., 95%, maximum] (from columns 7th to 27th) and the series IDs (28th column)

path:

Object of class "character" Inherited from Trajectories-class

filenames:

trajlist:

Object of class "list" Trajectories. Inherited from Trajectories-class

avd:

Object of class "numeric" adf p-values. Inherited from Trajectories-class

tmethod:

Object of class "character" Transformation method. Inherited from TransTrajectories-class

breakpoints:

Object of class "list" breakpoints, if used.

tavd:

Object of class "numeric" adf p-values after transformation, if used. Inherited from TransTrajectories-class

ttrajlist:

Object of class "list" Transformed trajectories. Inherited from TransTrajectories-class

tfilenames:

Object of class "character" Transformed trajectories names. Inherited from TransTrajectories-class

ct:

Object of class "numeric" Grouping information.

Accessors

In the code snippets below, x is a SegSeriesTrajectories object.

getTNames(x): Retrieves filenames from slot filenames or tfilenames depending on whether the series has been transformed.

getTraj(x): Retrieves trajectories list from slot trajlist or ttrajlist depending on whether the series has been transformed.

getBreaks(x): Retrives breakpoints (if any) from slot breakpoints

getAVD(x): Retrieves adf p-values from slot avd or tavd depending on whether the series has been transformed.

getSegments(x): Retrieves clustered segmentation data from slot smatrix produced by clusterSegments

Other methods

In the code snippets below, x is a SegSeriesTrajectories object.

diagnosticPlots(x): Generates the diagnostic plots of the wavelet denoising model residuals

getIntervals(x): Helper function to retrieve subpopulations and computes the intervals for each subpopulation after segmentation and clustering.

plot(x): Plots the final clustered segmentation data after clusterSegments

show(x): Displays summary of object, including inherited classes. This helps in recalling the analysis path taken to produce the current results.
