The connection function threshold volatility calculates the frequency of each unit falling within a certain range over more than one selected file. The upper and lower boundaries are set as percentage values of the maximum value. It is for example possible how often each unit has been selected as acchieving high index values between 70% and 100%. The output is a map that gives an idea which areas areas are most commonly selected as acchiving high index values.
Set the upper and the lower boundary of the threshold volatility dialog. The values correspond to the percentage of the maximum value within each file respectively.
