title: Converting non-stationary to stationary
body: <p>I have one data it is <strong>not stationary</strong>. I'm trying to make it <strong>stationary</strong>.
  I tried log transformation, BoxCox transformation, lag(1, 2 and 3) differences.
  No use of these transformations and differencing.</p>
  
  <p>I used <strong>adf test</strong> to test stationary in R.
  Can anybody tell is there any other method to make it stationary.</p>
