Interpretation of parameters in loglog-regression with scaled variables
Consider e.g the model $y = e^{\text{trend} + \text{seasonality}} \cdot \prod_{k \in \text{channels}} x_k^{b_k}$
where $i$ constrained $0 < b_k < 1$ (to capture diminishing marginal returns)

Interprete log(y) changes in regression
I oriented at this explanation of interpreting statistical outcomes:
http://www.princeton.edu/~otorres/Stata/
ln(Y)=B0 + B1*X + u ~ A change in X by one unit (∆X=1) is associated with a (exp(B1) - 1)*...

Interpretation of log-linear regression
The regression is
$$\ln y = \beta_0 + \beta_1 x_1 + \beta_2 x_2 + \varepsilon$$
I know there is an approximation, but what about the exact interpretation of $\beta_1$ in non-log terms of $y$?
This ...

Log-log linear model interpretation, when does the approximation not hold?
I read in the following post: Interpreting Log-Transformed Percentages in OLS that
In a log-log model, such as $\log(y) = b_0 + b_1 \log(x)$, I know that
with OLS the standard interpretation is a &...

Interpreting log-log regression with log(1+x) as independent variable
Is interpreting log-log regression with log(1+x) as independent variable the same as having log(x) as independent variable? 1% increase in x results in beta% change in y?
What is x has both negative ...

Can we compare coefficients from log-log and log-linear regression?
We have two regressions
$$
ln(Y) = \alpha_1 + \beta_1 ln(X) + \epsilon \tag{1}\label{1}
$$
and
$$
ln(Y) = \alpha_2 + \beta_2 X + \epsilon \tag{2}\label{2}
$$
In the first case, a 1% increase in $X$ ...
