Kalman filter[edit]

Hello and welcome.

Your editing of Kalman filter prompts an observation. Notice the difference between these formats:

the kth timestep

and also between these

the k-1th timestep

the (k − 1)th timestep

In the latter, the k is italicized; the hyphen is changed to a long minus sign, and some spacing helps legibility. Also, notice that I changed the section heading that said Extended Kalman Filter to Extended Kalman filter with a lower-case f (not sure that one was yours, though). That's standard here.

Happy editing! Michael Hardy 01:53, 31 Jan 2005 (UTC)

I see that you changed the header that said Kalman filter equations to Kalman Filter Equations. That is the opposite of conventional Wikipedia usage, as you'll see if you look at lots of articles; see in particular Wikipedia:Manual of Style. Michael Hardy 22:31, 9 Feb 2005 (UTC)

Please comment on the use of var(X) in Talk:Kalman filter - thanks! — ciphergoth 12:39, 2005 Apr 20 (UTC)

Kalman filter article messup[edit]

It seems like you've just messed up the Kalman article a bit. The whole content is repeated twice. Repetition is great for learning, but I don't think its appropriate here :) --Fredrik Orderud 01:10, 21 Apr 2005 (UTC)

Joint!![edit]

For gaussian noise independance also implies uncorrelated but in general this is not the case. Chrislloyd 15:59, 21 Apr 2005 (UTC)

This is mistaken.

Jointly Gaussian and uncorrelated implies independence.

Gaussian and uncorrelated does not imply independence. Michael Hardy 21:43, 28 Apr 2005 (UTC)

Michael, doesn't independance imply uncorrelated? I agree uncorrelated does not imply independence with out the words jointly gaussian. I wish i had been able to recall that fact correctly at the time it was discussed on the kalman filter talk page - i could have saved myself a lot of typing and head scratching!
