13.5 Interpretation of Regression Coefficients: Elasticity and ...
Ordinary least squares estimates typically assume that the population relationship among the variables is linear thus of the form presented in The Regression Equation. In this form the interpretation of the coefficients is as discussed above; quite simply the coefficient provides an estimate of the impact of a one unit change in X on Y measured ...

2 Answers. I would suggest using a generalised linear model (GLM) with a log-link function instead of directly log-transforming your variables; in R you can simply use glm with family= gaussian (link='log') to begin with. I say this because modelling the mean of the log-transformed variable (as you would do by simply taking the logarithms of ...

Logging only one side of the regression "equation" would lead to alternative interpretations as outlined below: Y and X -- a one unit increase in X would lead to a $\beta$ increase/decrease in Y. Log Y and Log X -- a 1% increase in X would lead to a $\beta$% increase/decrease in Y
FAQ How do I interpret a regression model when some variables are log ...
Very often, a linear relationship is hypothesized between a log transformed outcome variable and a group of predictor variables. Written mathematically, the relationship follows the equation \begin {equation} \log (y_i) = \beta_0 + \beta_1 x_ {1i} + \cdots + \beta_k x_ {ki} + e_i , \end {equation}

Log-linear Regression | Real Statistics Using Excel
Log-linear Regression. In Linear Regression Models for Comparing Means and ANOVA using Regression we studied regression where some of the independent variables were categorical. In this part of the website, we look at log-linear regression, in which all the variables are categorical. In fact, log-linear regression provides a new way.

How can I estimate relative risk using glm for common outcomes …
There are several options for how to estimate RRs directly in Stata. Two of these methods will be demonstrated here using hypothetical data created for this purpose. Both methods use command glm. One estimates the RR with a log-binomial regression model, and the other uses a Poisson regression model with a robust error variance.
Regression Log Transformation | Real Statistics Using Excel
We next run regression data analysis on the log-transformed data. We could use the Excel Regression tool, although here we use the Real Statistics Linear Regression data analysis tool (as described in Multiple Regression Analysis) on the X input in range E5:F16 and Y input in range G5:G16. The output is shown in Figure 2.
Poisson regression | Stata
ORDER STATA Poisson regression Stata’s poisson fits maximum-likelihood models of the number of occurrences (counts) of an event. In a Poisson regression model, the incidence rate for the jth observation is assumed to be given by r_j = exp (b_0 + b_1*x_ (1,j) + ... + b_k*x_ (k,j)) If E_j is the exposure, the expected number of events C_j will be
Econometrics and the Log-Log Model - dummies
You can estimate this model with OLS by simply using natural log values for the variables instead of their original scale. After estimating a log-log model, such as the one in this example, the coefficients can be used to determine the impact of your independent variables (X) on your dependent variable (Y).The coefficients in a log-log.
