Input
Specifies the worksheet location of the input data for this operation.
Provides a reference to the extent of the data available in the currently active worksheet. Use this range as a guide for typing valid extents in the Input Range 1 and Input Range 2 boxes.
Type in this box the range of cells containing the data you want to use as input for this command (first set of input series).
Type in this box the range of cells containing the data you want to use as input for this command (second set of input series).
![]() | You are only required to specify a second set of input series when you check the Cross Recurrence box. |
Check this box to indicate that the data specified by the Input Range 1 and Input Range 2 boxes is organized in rows as opposed to columns (the default)
Refer to Specifying Input Arguments for additional information on this subject.
Output
Specifies the worksheet location for placing the results of this operation.
Select this option to place the results of this operation in a new document workbook.
Select this option to place the results of this operation in a new worksheet.
Select this option to place the results of this operation starting at the worksheet location specified in the box to the right of this option.
Check this box to restrict this operation to the display of the recurrence plot only.
![]() | Recurrence plots are build to a maximum of 1024x1024 pixels. If the amount of information supplied for the command exceeds this limit, the given series are sub-sampled at equal time intervals to this number of vector points. |
Refer to Specifying Output Locations for additional information on this subject.
Embedding tab
Specifies how the selected series are organized within the input ranges.
Single Series
Select this option to indicate that the data specified by the Input Range 1 and Input Range 2 boxes represent individual series.
Multivariate
Select this option to specify that the input data (Input Range 1 and Input Range 2 boxes) represent multidimensional series as opposed to single series. In this case, the width of each series is specified by the Dimensions box.
Refer to Specifying Input Arguments for additional information on this subject.
Check this box if you want to calculate the recurrence plot and/or RQA statistics across two or more series.
Specifies the dimensions that are used for the embedding (Single Series), or the width of the series (Multivariate).
Specifies the time delay used for the embedding.
![]() | The Time Delay box is not available for Multivariate series. |
Threshold Corridor tab
Specifies the method by which distances are computed.
Loo - Max
Select this option if you want to use the Minkowski Max, , distance metric for measuring distances.
L1 - Manhattan
Select this option if you want to use the Minkowski Manhattan, L1, distance metric for measuring distances.
L2 - Euclidean
Select this option if you want to use the Minkowski Euclidean, L2, distance metric for measuring distances.
Specifies interpretation of the quantities specified in the Lower Limit and Upper Limit boxes.
Fraction
Selecting this option instructs Predictive Systems Lab to interpret the quantities specified in the Lower Limit and Upper Limit boxes as a fraction of the extent of the attractor(s) in question, in the range [0.0, 1.0].
Actual Value
Selecting this option instructs Predictive Systems Lab to interpret the quantities specified in the Lower Limit and Upper Limit boxes as actual distances within the attractor(s) in question.
Specifies the context by which the threshold fractions are interpreted for calculating the RQA statistics.
Global
Choose this option if you want to calculate the RQA statistics across all distances.
Local
Choose this option if you want to calculate the RQA statistics across points within the corridor distance only.
![]() | Specifying a Local Fraction Context for a Lower Limit of zero and an Upper Limit of one, has no effect on the results. |
Specifies the lower limit of the threshold corridor. Usually set to zero.
Specifies the upper limit of the threshold corridor. Usually set to 10% (0.1) of the attractor size.
Refer to Iwanski & Bradley (1998) for a good discussion on the subject of threshold corridors.
Recurrence Analysis tab
Specifies the minimum number of consecutive points that integrate a line in the context of RQA statistics.
Check this box if you want to calculate RQA statistics on contiguous data windows within the selected series.
![]() | If you check this box you will be required to specify a Window Size and an Overlap Type for the data windows. For example, specifying a Window Size of 200 and Overlap Type to Minimum, will calculate RQA statistics for contiguous data windows in the series that overlap by one point, while selecting the Overlap Type as Specified with an Overlap of 0.5 for the same Window Size, will calculate RQA statistics for contiguous data windows in the series that overlap by 100 points. |
Specifies the size of the data windows for calculating the RQA statistics.
Specifies how contiguous data windows overlap.
Refer to the notes under Windowing for additional information on this subject.
None
Select this option if you do not want overlap between contiguous data windows.
Minimum
Select this option to specify the minimum possible overlap, one point, between contiguous data windows.
Specified
Select this option if you want to specify the amount of overlap between contiguous data windows.
Maximum
Select this option if you want the maximum possible overlap, Window Size - 1, between contiguous data windows.
Specifies the amount of overlap between contiguous data windows as a fraction of the Window Size.
Colorization and Style tab
Check this box if you want to generate the recurrence plot as a contour map, instead of a bitmap.
![]() | This feature is only available for series of lengths of up to 512 points. |
Specifies the distance context that will be painted in the recurrence plot.
All Distances
Select this option is you want to apply the Color Style across the total extent of the attractor.
Corridor Only
Select this option if you want to apply the Color Style across the extent of the corridor only.
![]() | Color Context has no effect on Threshold plots. |
Specifies the way in which the recurrence plot will be painted.
Threshold
Select this option to use a threshold color to paint pair of points that fall within the corridor distance.
Gray Scale
Select this option to paint, using a gray scale gradient, pairs of points according to their distance.
Spectrum I
Select this option to paint, using a prescribed palette, pairs of points according to their distance.
Refer to Spectrum I Palette to display this palette.
Spectrum II
Select this option to paint, using a prescribed palette, pairs of points according to their distance.
Refer to Spectrum II Palette to display this palette.
Spectrum III
Select this option to paint, using a prescribed palette, pairs of points according to their distance.
Refer to Spectrum III Palette for a description of this palette.
Gradient
Select this option to paint, using a gradient of colors, pairs of points according to their distance.
Check this box to invert the order of the spectrum colors for painting the point pair distances.
Use this control to select the color with which to paint pair of points that fall within the corridor distance.
![]() | This feature is only available when you select the Threshold Color Style. |
Use these controls to select the start and end colors of the gradient to paint pairs of points according to their distance.
![]() | This feature is only available when you select the Gradient Color Style. |
