Hi everybody,
my problem is a variable (age) that I wish to enter into linear regression - but, the variable is not linear. So, I want to model it. But, it doesn't work so far. I already tried: log10, exp, ², √, and /1.
Is there anything else I could try? I already talked to a statistican and she had no more ideas, so this is probably a though one... :shakehead
The boxplot shows the variable in relation to the target variable. There is a sharp effect (rapid increase) during young ages and almost no effect of the variable (age) on the target variable in later years. Of course, I could just compute two separate models, but this is just my exit strategy. I'm using SPSS.
Looking forward to many brillant ideas!
