Webb29 juli 2024 · Normally (no pun intended), the difference between the two tends to be around half the variance of the returns in question. This is simply because the normal distribution (for simple/arithmetic returns) is symmetric. The lognormal distribution (of log/geometric returns) is not (because of the examples above). WebbWe have to take advantage of the fact, as we showed before, that the average of the natural log of the volumes approximately equals the natural log of the median of the volumes. Exponentiating both sides of the previous equation: V o l …
Webb16 maj 2024 · The log difference is independent of the direction of change Logarithmic Scales Symmetry Data is more likely normally distributed Data is more likely homoscedastic Reason 1: The log difference is approximating percent change Why is that? Well there are several ways to show this: One is presented below Webb16 nov. 2012 · Logarithm of a quantity really only makes sense if the quantity is dimensionless, and then the result is also a dimensionless number. So what you really plot is not log ( y) but log ( y / y 0) where y 0 is some reference quantity in the same units as y (in this case y 0 = 1 Volt). Similarly for exp and sin. Share Cite Follow
Webb25 okt. 2024 · In reality there's always a stochastic noise in the data. To see how it's handled let's first write the above equation in a difference form: Δ ln x t = ln x t − ln x t − 1 = r. One way to make this process stochastic is to add noise to the rate of change as follows: Δ ln x t = r + ε t ε t ∼ N ( 0, σ 2) Webb1 feb. 2024 · Suppose you want to compare price and volume vs time, try this: df = pd.read_csv('your_path_here') df.plot('Time', ['Price', 'Volume'], secondary_y='Price') edit: x …
