Select and Run Measures

This is the top window for measure selection and run. Starting from here the user can enter the different measure groups, select the measures and determine the measure specific parameters. When the selection is completed the user can press the "Run" button to start executing the selected measures on all the time series in the current time series list. Any subset of the listed measures in the different groups (or even all the measures) can be selected but the user should be aware of the computational cost for each measure, taking also into account the number and length of the time series in the current time series list.

Note that when a measure function is selected (by activating the check-box in the beginning of each measure line), the output for this selection may be a number of measures, one for each combination of parameter values (if parameters are to be specified). These are listed as distinct measures in the measure list and they are identified by the label of the selected measure function (this is the 10 character string in parenthesis after the descriptive name of each measure) and characters followed by numbers for each specified parameter (for the list of parameter notations, press the "Measure and parameter name notation" button in the main menu).

 

Linear Measures

The group of linear measures includes measures based on the linear correlation (autocorrelation), frequency (power spectrum) and linear models (only autoregressive models are included so far). To select measures in the specific groups press the associated button. Note that the Correlation group includes measures of linear and monotonic autocorrelation, i.e. in addition to measures based on the Pearson autocorrelation function measures based on the Kendall and Spearman autocorrelation function are included as well.  
 

Nonlinear Measures

The group of nonlinear measures includes measures based on the nonlinear correlation (mutual information), dimension and complexity (embedding dimension, correlation dimension, entropy) and nonlinear models (local average and local linear models). To select measures in the specific groups press the associated button.
 

Other Measures

The group of "other" measures includes simple measures of descriptive statistics (marginal moments) together with the Hjorth parameters and measures of long range correlation (DFA and Hurst exponent), as well as simple descriptive statistics of oscillation features extracted from the time series. To select measures in the specific groups press the associated button.
 

Load Measure Parameters

This option can be used in case the user wants to use a pre-specified set of selected measures and parameter values stored in a file with a special format. The file should have been created from this program (using the "Save Measure Parameters" option, see below). This facility can be helpful if the user wants to execute the same set of measures and parameters on different instances, or different set of time series.
 

Save Measure Parameters

This option allows the user to save the selected set of measures and parameters in a file of specific format. The user may load this file ("Load Measure Parameters" option, see above) if he/she wants to execute the same set of measures and parameters at a later stage (e.g. on a different set of time series).
 

Reset Default Parameters

This option allows the user to restore the default parameters for all measures.
 

Run

This button should be pressed when the user has selected all the measures (and parameters) and the measures will be executed on all the time series in the current time series list. Note that for each use of the Run button the measure list is cleared in order to be filled with the measure values from the new execution. Information about the progress of the batch execution of the selected measures is given in the "Running messages" text box. Note that the execution can be slow for some computationally involved measures, such as the correlation dimension estimation and the iterative local linear fit.
 

Running messages

Here the progress in the batch execution of the measures on the time series in the current time series list is displayed. For each measure, the measure name appears in a new line followed with 1 (for the first time series being executed), and dots and number (1+multiple of 20) that indicate the number of the time series being processed. For example, a snapshot for the execution of the "False Nearest Neighbors" measure (for a set of parameter values) processing the 24th time series in the current time series list would look like the following:

False Nearest Neighbors : 1...................21...
