Syntax: Tri(minimum, mode, maximum, stream)
The triangular distribution (continuous) is typically used as a rough model for the time required to perform some task when no real-world data are available. A triangular distribution takes on values in the finite interval [minimum, maximum] (minimum >= 0.0, mode > minimum, and maximum > mode), with values near the mode being most likely to occur. Subjective estimates of the three parameters are obtained from subject-matter experts. The mean of a triangular distribution is only equal to the mode when the distribution is symmetric.
Stream allows you to specify the random number stream for the distribution. There are 215 streams. Stream 1 is the default. See Seeds or Appendix D of the User's Guide for more information.
