"Channel"

When you use the Automatic method, you specify the number of classes. DIAdem calculates the missing parameters from the maximum and minimum values of the channel to be classified. If you use the Channel method, DIAdem uses the values of the specified channel as class limits.

"absolute"

"relative"

The absolute class frequency H_i of the i-th class K_i for i=1, 2, ...p for even numbers p of the created classes is equal the number of observation values in the class K_i. The relative class frequency hi of the class Ki is then 1/n multiplied by the absolute class frequency.

with n = Channel length

You can enter a hysteresis for classification methods that use one parameter and for the rainflow classification method in order to avoid slight fluctuations. DIAdem ignores an oscillation that occurs only within a class even if you do not set a hysteresis. Select the highest number of classes possible to keep the class width low.

If you select the channel method to define the class limits, the classes can have different widths. The hysteresis does not use the different class widths because DIAdem calculates the hysteresis as a percentage of the average class width.

If this flag is set, DIAdem counts the values includes the values that are outside the class limits in the outer classes.

At least 10 classes are required. DIAdem includes values that are on a class limit in the next class up. DIAdem does not use values on the highest class limit.

This parameter sets the number of classes of the quadratic matrices in the rainflow classification. The rainflow classification has up to 128 classes.

DIAdem calculates the width of a class interval as the quotient of the range and the number of classes. If you select Channel to specify the class limits, the classes might have different widths.
