Excel sheet ideas:

DTMC:
vector*pmat; Error: transpose
pmat powers; Error: too small
pmat squared; Error: actually powers
steady-state; Error: transpose?
simulate; Error: rand->column mapping
collect-stats; Error: reverse jumps

Poisson Proc:
Binomial Process; Error:
Arrival times of PP are Unif. order stats; Error:
Non-Homogeneous Poisson arrivals
	* wrong approach: inter-arrivals Exp(lambda(t))
	* right approach, small mistage

CTMC:
convert SMP to rates
convert rates to SMP
simulate, as SMP; Error: times rate instead of mean
simulate, as rates; Error:
steady-state, as SMP; Error: forget to normalize
steady-state, as rates; Error:
transient, (I+R/n)^n; Error: ((I+R)/n)^n
transient, Euler; Error: times h vs. divided by h
transient, RK; Error: apply 1/6 to only the first term, not sum
transient, RK; Error: \vec{k}_{2} or _{3} based on wrong time or space point.
