penalty0 {MQMF} | R Documentation |
penalty0 enables the adding of a large penalty as one approaches 0.0
Description
penalty0 allows for the option of adding a large penalty as a parameter approaches 0.0 . See negLL1 for example code that contains such a parameter. For example, when fitting an spm sometimes the optimal mathematical model fit can occur by depressing the r value to 0 or even go negative. Input values < 0.006 begin to generate large values as one goes smaller. The examples below illustrate this.
Usage
