I am a retired software developer. I retired at the end of 2003 and since then my computer programming activities have been for recreational purposes. I find Mathematica excellent for that.

I started using Mathematica in 1997 (Ver. 3). I am currently using Ver. 9. Although I have used Mathematica for all kinds of stuff, I use it mostly to pursue my long standing interest in Euclidean geometry, both in its classical Greek synthetic form and in its more modern analytical/transformational form.

comment A Problem on Evaluating the best fitting distribution and confidence intervals within a Custom Distribution
The error message is clear -- you have defined cdfw as a function of three variables, but you are passing it eight arguments when call it.

comment What's the complete list of file name extensions used by Mathematica?
@qazwsx. I have not encountered .wlt files. In V10, a testing notebook template was introduced to support testing, but such files are just .nb files. However, such files might make testing files with a different extension unnecessary and perhaps deprecated.
