Ch.2 Exercise 3.1 #6

Closed bugerry87 closed 4 years ago

Have you mixed up the transition-matrix for day 3-4? Although, day 5 is correct anyway because day 4 eliminates the error.

E.g.: My approx results for P(X3=i | z{2:3}) = (0.599, 0.282, 0.0)

Thx for your great work!

@bugerry87 Thanks for your support. Indeed there is a mistake but do we agree on this one (day 2) ?

P(X₂=i | z₂) = (0.70,0.30,0.00)

I corrected some calculations in ex3. Do not hesitate to let me know if this does not agree with your results (in any case the numbers you provided do not sum up to 1 so they cannot be correct).

bugerry87 commented 4 years ago

Oh sorry for the late reply. Yes, I confirm with your results now. In my case I might have made some typo within the normalization.

So thx, I will also correct my version and put yours to my references.
