Troubleshooting for Model Fitting

It can be that the model fitting fails. Here are some ideas for troubleshooting.
Technical problems:
- Does your data contain negative values or values close to zero? The GAMLSS framework is not made for that case and you can only solve this issue by converting the data into positive values.
- Do your column names contain special characters like "ß"? You better change the column name to a word with standard characters.
Mathematical problems:
- Is your data sparse "at the edges" (left or right)? The fitting might fail because of mathematical issues. Exclude single points at the edges to avoid this issue.
