How to log transform 0s? (or how to deal with these 0 values?)

[leungwinnie]

There are some spend data that I want to include in my model as dependent variables, these however are 0s at some weeks.

Since log cannot transform 0s, does it make sense if I manually replace these failed transformations to 0?

And many thanks for your helpful article!

Usually, log transformation is x_transformed = log(x+1)
