Data Processing Report Options
The red triangle menu for the Data Processing report has the following options:
Cleanup
A submenu of the following data cleanup options:
Remove Zeros
Removes observations with zero values. If there are no zeros in the data, an alert appears, indicating that no zero values were found.
Remove Value
Displays a specifications window that enables you to specify a value to remove from the data.
Remove Selected
Removes observations that correspond to rows that are selected in the data table.
Remove Unselected
Removes observations that correspond to rows that are not selected in the data table.
Note: The remove options exclude the specified observations from the analysis report, but the observations remain unchanged in the data table.
Transform
A submenu of the following options to transform the output data:
Center
Centers the output.
Standardize
Standardizes the output by centering and scaling the data to have mean 0 and variance 1.
Range 0 to 1
Scales the output to lie within the range of 0 and 1.
Square Root
Transforms the data by computing the square root of the output. The output values must be nonnegative.
Square
Transforms the data by computing the square of the output.
Log
Transforms the data by computing the natural logarithm of the output.
Exp
Transforms the data by computing the exponential function of the output.
Negation
Transforms the data by negating the output.
Logit
Transforms the data by computing the logit function of the output. The output values must be between 0 and 1.
Align
A submenu of the following options to align the input data:
Row Alignment
Replaces the input values with the row number.
Align Maximum
Aligns the functions using the observed maximum output value for each ID level. The input value associated with the observed maximum output value is set to zero for each ID level and the other input values are shifted up or down based on the difference between the observed maximum and zero.
Align Minimum
Aligns the functions using the observed minimum output value for each ID level. The input value associated with the observed minimum output value is set to zero for each ID level and the other input values are shifted up or down based on the difference between the observed minimum and zero.
Align Range 0 to 1
Aligns the output functions such that the range of the input values is 0 to 1.
Tip: Align Range 0 to 1 is particularly useful when you fit a P-Spline model.
Dynamic Time Warping
Aligns the output functions using dynamic time warping (DTW). DTW is a function alignment technique that finds an optimal warping to align two or more functions together. When you select the DTW option, a Select Reference Function window appears. Use this to select the reference function. The reference function is the function that the remaining functions are aligned to.
Once you select a reference function and click OK, a warping function plot is shown along with a list for the remaining query functions. On the warping function plot, the reference function is on the y-axis and the selected query function is on the x-axis. Deviations from the red diagonal line (y = x) indicate that the inputs of the query function have been warped for better alignment.
Dynamic Time Warping Options
Plot Warping Functions
Shows or hides the warping function plot. On by default.
Save Distance Matrix
Saves the distance matrix to a separate data table. The distance matrix can be useful for clustering the functions. The distance matrix data table contains a hierarchical clustering script.
Save Warping Functions
Saves the warping functions to a separate data table. Each row of the data table contains the DTW adjusted input variable, the original input variable, and the ID variable.
