bibtexerrors

I am getting the following error message when I run my code:

! Missing } inserted. }
l.116 \end{thebibliography}

I have read previous questions like this on here which say the error is in my bibliography and not main code but I cannot find a missing bracket in my bibliography or anything else which could be causing the issue before line 116.

Here is my bibliography; (I have put < line 116> to show you where this is, please note this is not apart of my actual code)

Best Answer

Well, you have several mistakes in your given bib code. Let us look to bib entry ParetoDist2011. The corrected version is:

@misc{ParetoDist2011,
  TITLE        = {The Pareto Distribution},
  YEAR         = {2011},
  howpublished = {\url{https://statisticalmodeling.wordpress.com/2011/06/25/the-mean-excess-loss-function}},
  LAST_EDITED  = {23 June 2011}, 
  NOTE         = {"[Online; accessed 30 August 2017]"},
}

You missed an \before url{, the blank in LAST EDITED results in an error message (missing =). In other entrys you masked in urls % with \%. After loading package url or hyperref that is not longer needed ...

The following MWE compiles without errors and only one warning (okay, commes from used package filecontents to keep bib file and TeX code together in one MWE):
