A simple threshold function. When you use this function, you define a threshold value, and enter this into the 窶彡窶 parameter. If the input value is greater than or equal to the threshold, the output value is equal to the 窶彗窶 parameter. Otherwise, the output value is equal to the 窶彙窶 parameter.
This function is useful for converting a variable to e.g., an indicator. By letting 窶彗窶 be 1 and 窶彙窶 be 0, the output value is the indicator for the event that the input value is greater than or equal to the 窶彡窶 parameter.
Note that the 窶彗窶 parameter does not need to be greater than the 窶彙窶 parameter. It is perfectly OK to e.g., let 窶彗窶 be 0 and 窶彙窶 be 1.
