    Comparing normal distribution divided by normal distribution

    We take the average of cells with A only: x1 + x2 + x3 / 3 Then we take the average of cells with A + B: x4 + x5 + x6 / 3 So the ratio A+B / A = (x4 + x5 + x6) / (x1 + x2 + x3) 1 - (x4 + x5 + x6) / (x1 + x2 + x3) = the reduction in proliferation.Yes, G's are generations. G1 is the parent...

    Comparing normal distribution divided by normal distribution

    Let me give you an example data set. Cell A only G1 (parent): 8.89% G2: 8.47% G3: 14.94% G4: 23.85% G5: 24.27% G6: 15.66% G7: 4.12% The proliferation index (average number of divisions) is calculated as sum i*Gi / 100% = 4.57. So if we started with 1 million cells, the final population is...

    Comparing normal distribution divided by normal distribution

    Instead of "therefore", take it as "In summary," Let me help clarify the rest: I am measuring proliferation as the average number of times that the cells divide. We track cell division by labeling the cells with a dye called CFSE. Parent cells will have 100% CFSE levels, 1st generation 50%...

    Comparing normal distribution divided by normal distribution

    Thanks for your replies! To clarify (please excuse my sloppy notation): This is true. However, I do not think X-Y is normal. After doing some more searching on google, X and Y are Cauchy distributions. I was wondering if there was a test (along the lines of t-test or F-test) for this...

    Comparing normal distribution divided by normal distribution

    Hi everyone! I have a question on how to compare two distributions. I'm currently a 2nd year biology grad student, and I'm trying to compare a parameter that evaluates the efficacy of a cell type. The math problem is this: Let X and Y each be an average of three variables divided by an average...

    QM Free Particle Approaching Infinite Barrier

    Solved... i think. It's just Psi(x) = B sin kx Homework Statement Consider a free particle psi(x) = A*e^(ikx) approaching an infinite barrier from the left: V = 0, x < 0 and V = oo, x >= 0. For this problem use only the time-independent Schrodinger Equation. a. Find the probability of being...
