In triangle: Distribution Functions and Parameter Estimates for the Triangle Distribution

version 0.1 (2006-10-20)

• Changed the rtraingle and qtriangle functions in response to an excellent bug report from Dr Michael Scroggie ([e-mail]). The bug involved the conditional logic in the inverse CDF so that when the "a" and "c" parameters were equal, rtriangle would return a vector of "a".

version 0.4

• Changed the license to GPL >= 2 according to a Kurt Hornik email

version 0.5

• Changed the filenames to be portable

version 0.6 (2009-03-25)

• added the log scale triangle function

version 0.7

• Added the manual entry for the logarithmic triangle

version 0.8

• Changed the arguments for dtriangle and dltriangle to be an "x" instead of a "q" based on a suggestion from Randall Pruim. Also, changed the default for the triangle mode to be 1/2 of the base instead of 1/2 (or 10 for the log triangle) based on Randall Pruim's suggestion as well.
