Replace missing values with a fixed value

Given a basetable that has a predictive variable "total_donations", indicate the total amount of donations made by each donor in the population. If a value is missing for this predictive variable, it means that this is a new donor that did not make any donations yet. In this case, logical reasoning can be used to know by which value we should replace missing values.
