A simple threshold function where the threshold is a linear function defined by the 窶彡窶, 窶彭窶 and 窶彳窶 parameters. Instead of a single constant threshold, the threshold has the form:
Threshold = c d + e
If you specify numbers for all the parameters, you probably do not need this linear function. In such cases you can just replace the more complex threshold by a simple constant threshold, and use the Thresh1 function instead.
However, if some of the parameters are references to nodes, the Thresh3 function provides a little bit more flexibility.
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.
Like the Thresh1 function, this function is also 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 threshold.
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.
