    Proper likelihood function of the ratio of two spectra

    Hello PF'ers, I am doing an unbinned likelihood analysis where I am analyzing the ratio of two spectra: \[ \frac{S_{1}(E)}{S_{2}(E)} = F(E) \] and each spectra, \[ S_{1}, S_{2} \] has its own data set. My first idea was to take the function, \[ F(E) \] and divide by the integral of...

    Knee deep in Bayesian statistics and

    Hello all, To just begin, I am having a lot of trouble keeping my brain in the Bayesian view and not letting it revert back to a Frequentist way of thinking. Not to mention having troubles with unbinned MLE estimation. If I say something wrong, please let me know. My questions are...

    I in understanding the measurement process.

    Hello everyone, I am in my Undergraduate Quantum Mechanics class right now and it has been great fun so far. However, I am still hooked up on a topic that just does not click with me, but is of vital importance. I need help in understanding what the wavefunction does and why it...

    Sorry, but I'm in dire need(Proofs)

    Hello, I need some help. Could someone kick me(hard please) in the right direction here? Here are the statements I need to prove: 1) If g of f is injective, then f is injective 2) If g of f is subjective, then g is subjective where g and f are functions where f:A->B and g:B -> C where A,B...

    Can Canonical Transformations Solve Velocity Dependent Potential Problems?

    Thanks Physics Monkey! Thats why none of the books took it into greater depth! I'll read up more on the Hamilton-Jacobi equation and if I have any questions, I'll come back. However, you answered my question and I am extremely grateful.Many thanks, ~QuantumDefect

    Can Canonical Transformations Solve Velocity Dependent Potential Problems?

    Hello, I've looked through a couple books on this subject and found the basic theory but none actually apply it to a problem. I was wondering if someone would be so kind as to maybe do a practice problem for me? The reason I say this is because I have a homework problem and have...

    What are you currently reading?

    Im currently reading a jumble of books. I am almost done with Lanau's Mechanics text, still have awhile on Bohm's Quantum Theory and a Geometric Algebra text I've been slowly working through. However, I don't have much time for outside reading with my studies.
