Statistics - comparing goodness of fits
|
| |
I have sets of weighted empirical distributions E and normal distributions N. Each distribution E_i is associated with (derived from, somehow) an N_i (each N_i has a different mean/std). I need to compare each E_i to its associated N_i, and obtain some measure that would let me say something like "E_1 is closer to N_1 than E_2 is to N_2." In other words, I want a number that establishes how good a fit is each E_i to N_i, and be able to compare (e.g. sort?) these numbers to draw conclusions.... more »

Spin of Quantum Particle and Gravity Mass. (? !) It is possible to say : that Physicists agree that the state of spin exists - but they don’t know what the cause of spin is. === . Questions. 1. Where does the ZERO-SPIN come from ? Where does the Angular Momentum of the particle derive from? Does the ZERO-SPIN hide into every particle or come outside?... more »

Numbers in array and its exponents ( congruence operation )
|
| |
Hi all, The question is in the end. Introduction: ============= Another way to see congruences is to put the numbers in an array of width n. In the following example n is 5: col 1 2 3 4 5 -------------------------- 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20... more »

The accuracy of the Calculus
 
|
| |
In the abstract realm of polynomial functions there is exactitude. There is a zero point derivative. But in real world problems(physics) there is not complete exactness. To find a slope you hone in on a infinitely small part of the real world curve but you cannot make it infinitely small. That would require infinite calculations so you... more »

... We can discuss that later. Meanwhile, let's look at the point now being made: ... Regardless of how the Compton Effect works, the point is this: The Compton effect is an explanation of how a red shift could happen without any expansion of anything at all, thus without any big bing. ... The point is: If, as science believes, matter can be made from... more »

Fixed odds bet
|
| |
Q: Find a Black-Scholes closed formula to price this fixed odds bet. I want to win N if over the next M days, the P has a high-low range (exceeding/not exceeding) Q points. For example: I get $50 if over the next 5 days the FTSE100 has a high-low range exceeding 2 points. For example, if the FTSE100 has a range of low=5,251.41 and high=5,253.94 over the next 5 days, I get $50 (because high – low = 2.53 > 2).... more »

Do you believe in Physics ? You don’t have to be so sure. Why ? === . How does Physics look now? ...The basis of the Physics consists of: 1. Abstract ‘ inertial movement’. 2. Abstract ‘ideal gas and ideal particles.’ 3. Abstract ‘absolute black body.’ 4. Abstract ‘entropy’ 5. Abstract SRT negative 4 - D space,... more »
