I am log scaling my whole dataset in log base 10. When I do this I get -infitity for the minimum value.
I am wondering how I can get rid of this -infinity?
I have been advised to add a small value number inside the log to get rid of this like:
log10(dataset + 0.01)
This does get rid of the -infinity but I'm unsure does this skew the data or is it the wrong thing to do?
Also,if this is the right method, does anyone have any tips on how to decide what number to use e.g. 0.01, 0.1, or 0.001?
