Apparently, it is so. I used this online text analysis tool that takes your writing, and compares it with a battery of literary greats. Amazingly, Lovecraft is one of my favorite writers. While I am nought to deliver references to the Old Ones nor to summon the great Cthulhu, I am honored and surprised to receive the comparison.
That being said, I have no idea what kind of algorithm this site uses to generate its comparisons.
