The plot log of volume versus log of price is
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.

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) Webb21 aug. 2024 · 1. Your true model being. (1) q = p α e β x 1 + γ x 2. for conveniency you made it linear using a logarithmic transform. (2) log ( q) = α log ( p) + β x 1 + γ x 2. But you must take care that these two models are not the same since you minimize with respect to the parameters α, β, γ two different objective functions.
