Hi I recently got into statistics... I am not too sure if this is the correct place to ask, I have included pictures as well
- Can I test "age of used vehicle" as independent variable against "selling price" as dependent variable in a simple linear regression?
- Is my residual plot as shown weird in any way? because "age" in my dataset only have values from 0 to 25 , I was wondering if it would be okay ( as values generally line up vertically) compared to when i use other variables such as " mileage" where the residual plot seems more scattered and do not line up ...
- My p-value of intercept is 0, is that considered significant and okay , or is there something wrong?
