  • $\begingroup$ I think you will find the information you need in the linked thread. Please read it. If it isn't what you want / you still have a question afterwards, come back here & edit your question to state what you learned & what you still need to know. Then we can provide the information you need without just duplicating material elsewhere that already didn't help you. $\endgroup$ – gung May 2 '17 at 16:01
  • $\begingroup$ I want to understand you my question by giving example...suppose my lab value is my dependent variable and age is independent variable, and I got the R2 value 0.028 and P value 0.012.Now i don't understand how to interpret this R2 value? second thing I have the idea about the R2 value indicates how much of the dependent variable can be explained by the independent variable. Can you please brief me the interpretation.... $\endgroup$ – iva May 3 '17 at 4:33
