blog posts per year: 2013 update

As the year ends, it's time to check on my post rate for 2013... I plot the accumulated posts per year by month:

posts per month

2013 is a purple line. There's a weak period following my injury in June, but then I had a burst of inspiration, and I ended up right up there with 2009 and 2011. 2010 was the most productive year, whereas 2012 was a slow year.

Here's the totals by year, along with a trend line I established last year, as well as a revised trend line:

2013 was tied with 2009 for 2nd most after 2010, while 2011 was only one post less for 3rd. I recovered from the reducing post trajectory I seemed to be following last year.

The new fit uses a somewhat different formula consisting of two components: a hyperbolic tangent for the upward transient followed by an exponential decay. My 2012 formula uses a linear ramp for the upward transient, but hyperbolic transient is better, as it saturates:

posts = 169.2 tanh [ 1.13 ( year - 2007.89 ) ] exp [ -0.063 ( year - 2007.89 ) ]

Here's months where I've posted at least 15 times:
