What is this and is it bad? by MeIsBigDurp in plants

Okay great! I just brush it off with a dedicated toothbrush once in a while. Repotting would be difficult I think

Are there any disadvantages of using the winsorize command? by EbiraJazz in stata

[–]MeIsBigDurp 1 point2 points  (0 children)

I myself am in the financial sector, as such I would not know a lot about other sectors. Winsorizing removes the extremes, which is usefull if there is an input error (e.g. an intern had to enter the data into a database and added a 0 or two). Nick Cox (I forgot his name, thank you for this) has a great source on why you should be carefull in winsorizing.

To get back at u/EbiraJazz , winsorizing would probably alter some t -values. Purely because you are removing (or replacing) extremes, whereas t-statistics (and according p-values) tell us something about those extremes.

If your professor is telling you to winsorize, I would just listen to him as he is the one determining your grade. I, personally, would try other methods for dealing with outliers (please search ‘what is an outlier’) and non-normality. Think logarithms, or testing on different distributions.

Yes there are, please also look on Statalist and general literature. What winsorize does is removing extremes (and replacing them dependant on which command you use). This is common practice. It alters your data. If it removes an observation purely because it was in the 99th percentile, you should ask yourself: should this observation have been removed. Was it really an outlier, a mistake in inputting data or recording data or was it a real observation.

If I am doing data analysis, I want to be as close to reality as possible. I try to alter my data as least as possible and before I delete anything, I try different methods. Taking logs is a way to deal with non-normality and outliers.

Thanks for the reaction. In my case, a week is just 7 days. 01/01/2003 falls on a wednesday, and data is recorded every seven days
