1. ### Outliers Parametric model

To conclude, I tried numerous transformations and the one that worked best was the box-cox approach. An example of it being implemented can be found here: https://www.kaggle.com/rtatman/data-cleaning-challenge-scale-and-normalize-data . I'd like to thank everyone for their feedback.
2. ### Outliers Parametric model

I can only upload this in txt format and its quite a small sample. the full thing can be found here as a csv: https://ufile.io/vgxm1 The goal is to construct a regression model to predict the funding of campaigns based on the other input variables. Even some pointers for non-parametric...
3. ### Outliers Parametric model

Thats a great observation Dason. Didn't think of that. Unfortunately for me this puts trimming out of the question. Any ideas on how to proceed? Thanks
4. ### Outliers Parametric model

Hi, thanks for replying. That was my impression as well. Here is the link to the data; https://ufile.io/vgxm1 4 features of crowdfunding campaigns on Kickstarter: ID, Backers Funding Goal (numeric) The data is raw, so I can post a jupyter notebook tomorrow if that helps. However it should...
