# How to denote a simple slope coefficient (interaction)?

I'm using sslope in stata to test the linear relationship between x and y for different values of my moderator. The output of sslope provides me with a significance level and a coefficient. As far as I know, a simple slope coefficient represents the slope of a regression line for a specific value of my moderator. I report standardized coefficients (betas, "b") in my regular regression table. However, I'm not sure how to report the coefficient provided by sslope. Should i denote this coefficient also "b"?

• What do you mean by "standardized coefficient"? Jul 8, 2019 at 10:01
• betas as provided by the "beta" option in regression in stata. Jul 8, 2019 at 10:49
• You are mixing a lot of notation: simple slope coefficient / interaction / standardized coefficient. Which is it? Jul 8, 2019 at 11:05
• Indeed, I am confused. As far as I know, a simple slope is the slope of a regression line for a specific value of the moderator. The module "sslope" in stata provided me with this slope. My question is, how do I denote this slope/coefficient? Jul 8, 2019 at 11:34
• Can you post your output? Are you just interested in how to write this up in a scientific paper? Jul 8, 2019 at 20:00

I don't know what sslope is but it reminds me of linear regression, where we build a model $$Y=\beta_0 + \beta_1 x + \epsilon$$ where:

• $$\beta_0$$ is a constant.
• $$\beta_1$$ represents the slope of the line that best fits the data.
• $$\epsilon$$ is random noise

If this is the case, I would go for $$\beta_1$$ as the symbol for that coefficient. It there is no intercept (at $$X=0$$ we have $$Y=0$$ too) I would go for just $$\beta$$
