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). 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)

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.

Axes using logarithm scales can't represent negative numbers or zero. The reason for this is it's not possible to get these values by raising a base number to any power. The lowest possible logarithm value on a log scale is zero.
