1) data sparseness & overdispersion, do they connect? 2) if we collapsed/combined some categoria (rows, collumns, cells) for the sake of the parsimony & inerpretability & agriment with X2 assuptions (mne>=5 (3?)), minimization of overdispersion, etc., ... does a some "stop" rules exists or may be considered?
First of all, thank you so(×2) much for uploading this lectures course on linear algebra. Time stamp: 37:20. I would prove uniqueness of additive identity in the following way: let 0 and 0' be additive identity of V. By definition of additive identity, 0=0+0'=0'. Thus 0=0'.
It’s 2022. I’m struggling in upper-division Proof-Based Linear Algebra. I earned an A in lower-division Linear Algebra since it was computational-based for the most part, but writing proofs is a whole another beast. This comment may be years late, but this video has been very helpful. Thank you for sharing.
I am endlessly grateful for you sharing these lectures. Thank you so much, this playlist has exposed a lot of my unknown unknowns that have been haunting me for years.
I think there is another proof of Riesz theorem (showing that a given function is an isomorphism of same-dimension spaces), which is a little bit more direct. Thanks a lot for your video, the definition of adjoint is very clear !
Words for the ages 30:10 " There is no such thing as missing data. Just a misspecified model." I haven't seen this topic presented this way, I really liked it. Got pointers for reading up more on this presented this way?
I have a question. Is there a precedence of taking a random sample of one category of the dependent variable so as to have similar proportions to the second for a three category dependent variable. My category proportions are 0.77, 0.20, and 0.027. Is there any other way to model the three category dependent variable for these proportions.
I tried other videos on youtube and the audio works fine, but this set of videos have sound only on the right side of the headphone. Is there a problem with the audio?
Hi thank you for the great lectures, in 23:00 we do not need to assume u_1 is different from zero , since we already made the assuption that the u's are linearly indep . amazing teacher !,I hope you can do lectures on more algebra topics ! or any other advanced math topics. subsribed to this channel :)
where is he? if it is possible to tell me this in order to look for more related information. I consider their classes really impressive, but to start I need some source with easier information to process. thank you
I don't think so. The notation he's using is different, and the topics aren't ordered in the same way. In any case, these videos are a great supplement to Axler. The Algebra 1M videos put up by Technion are also a great resource to use with it.
