What functions or computation or methodologies can we use to classify landslide susceptibility (high, moderate, low) for weight of evidence modeling? For example values for low susceptibility is -0.90-1.20; moderate, 2.00-5.00; high, 5.01-6.00. How do we get them? Thanks!

Class boundaries are often chosen somewhat arbitrarily. There is no golden rule. You set class boundaries based on your data and depending on the goal of the susceptibility map. You might for example decide that only 5% of all landslides should be located in the low susceptibility areas and at least 75% in the highest class.
Similarly, you can use 3 susceptibility classes, or 5, or any other number that makes sense for the purpose of the study.
Dear Alwin Dueza Robel
You can use Arcmap or any software allowing to do the spatial analysis, but before all it is necessary to make the inventory and the identification of the instabilities of the grounds, then to characterize, to determine and to classify the conditioning factors, and finally to make the necessary statistics ( calculation of weight of evidence) ...
