Sen (2012) proposed the innovative trend analysis methodology and gave its fundamentals in a simple way based on logical deductions. Later, this methodology has been applied by many writers to different data as mentioned by Kisi and Ay (2014) and Kisi (2015), who also implemented the same methodology. In one of illustrations in their paper (Kisi and Ay, 2014) there are incorrectly scattered data and this comment includes the correction for the illustration. Additionally, Kisi's (2015) application of innovative trend method, as explained in detail by Sen (2012, 2014, 2015), has invalid confidence limits (bands) and the invalidation is explained in the comment.
