Thanks for your answer, but the problem is i don't now the min and max values. I want to drop the observations if they are under 2.5% and over 97.5% of the maximum earnings. Boris This would have been useful to state in your original question! Its not that hard though... sysuse a...
How to Count Number of Observations in R Using thenrow()Function While the combination ofwith()andsum()functions provides a flexible approach, another straightforward method for counting observations in R involves the use of thenrow()function. Thenrow()function directly returns the number of rows...
Remember that outliers aren’t always the result of badly recorded observations or poorly conducted experiments. They may also occur due to natural fluctuations in the experiment and might even represent an important finding of the experiment. Whether you’re going to drop or keep the outliers ...
this is an outlier because it’s far away from the rest of the points”. Your data set may have thousands or even more observations and it is important to have a numerical cut-off that differentiates an outlier from a non-outlier. This allows you to work with any dataset regardless of ...

Also, given the limited period of analysis, we do not have the same amount of information for each New account, i.e., we collect fewer observations for those created toward the end of the collection period compared to those created at the beginning, and the length of the collection period...
I want to find the change in income across each round. So, I would like to create a variable incomedifference where: obs 1: incomedifference = 0 obs 2: incomedifference = 5 (10 - 5 = 5) obs 3: incomedifference = -4 (6 - 10 = -4) ...
