I'm planning to do logistic regression with my dependent variable as either with injury or no injury with one of my independent variables as average computer use.

I have attached a sample distribution of the average computer use - majority of data points are close in the .3-.5 hour range then another peaked in the 2.9-3.1 range.

Questions:

  1. Do I need to transform this data first before I run the logistic regression? I noticed that my other independent variables also exhibit this distribution shape.
  2. There seems to be a lot of outliers after the 6 hour range - how should I treat them?

Any suggestions or comments will be appreciated.

Thanks,data distribution

Having a normal distribution isn't a prior assumption when dealing with logistic regressions. So you don't necessarily have to transform anything.

And depending on how the outliers affect your results or assumptions it would be alright to drop them.
