I think there is a more serious issue here than the use of stepwise regression
but the use is a must for me ! how can i get 0.05 p values means significant variables using stepwise ?
Science is not a quest for
p < 0.05. Science is a quest for discovering repeatable and understandable patterns in our world. If you go into research looking for
p < 0.05, you will find it with enough effort. Unfortunately, to do so, you sell out the soul of true science, and your results will no longer be scientific.
The idea between the
p < 0.05 threshold is to guarantee that at most $5\%$ of research findings are false positives. But this guarantee makes a lot of assumptions about the honesty and integrity of the scientists using the statistical tools. Dredging your data to find
p < 0.05 is about the worst thing you can do, it annihilates all of the guarantees the statistical framework is supposed to provide.
So yes, we could tell you how to torture your data until you get the magical
p < 0.05, but we will not do so. To do so would be to sell out the thing we truly love, science.
