Uniform distribution and two points

<t>QuoteOriginally posted by: pk14I think for your simpler case, MLE only tells you b>=X.Nothing more because the distribution is uniform.I don't get why the MLE tells nothing more, "because the distribution is uniform" ?My thinking was that the probability of drawing the X, which we actually saw be...

Uniform distribution and two points

<t>Let's try something simpler first :A Uniform distribution extends over [0,b]. I chose 1 point randomly and call it X.Given X, what can I say about b? Answer : (1) b >= X and (2) the best estimate for b, using MLE approach is that b=X.I think the same conclusion results whether you choose 1 point,...

Rebuild Dependency Tree (in Excel) using VBA

<t>Manually, I can rebuild the Dependency Tree in Excel using CTRL+ALT+SHIFT+F9 (pressing these 4 keys together from the keyboard).How could I rebuild it automatically from VBA ?(Apart from using the SendKeys command, which might actually work too .. but will interfere in my working on the same PC o...

call vs put

<t>Trying to reason this out intuitively, I could think of only one reason:The maximum payoff on a put is capped at K. (upper bound of Max(K-S,0) is K).However, there is no upper bound on the payoff on the call option. Max(S-K,0) can be a very large number (though probabilities will get lower as the...

Nice inequality - two-liner!

<t>QuoteOriginally posted by: SPMarsInstead I'd rather see the max doesn't occur on the boundary by setting one of the variables as -3/4 and then the problem drops a dimension and we can either use 2-D Lagrange multipliers or work directly. Once this is done we do indeed find the max must be at x=y=...

Nice inequality - two-liner!

<t>If we release the first constraint i.e. a,b,c> -3/4 then do we get any relief on the upper bound of 9/10 which applies on the expression of interest. Also, isn't it also true that the lower bound on the expression of interest is -9/10 (with or without the a,b,c>-3/4 constraint) ?If the upper boun...
