Test whether the sum of two coefficients is significantly different that zero in indicator r...
I am using indicator regression with an interaction term to compare the slopes to two groups. … Based on how I set up the regression:
When $X_2 = 0$, then the $slope_0 = \beta_1 $.
When $X_2 = 1$, then the $slope_1 = \beta_1 + \beta_3 $. …

log-transformation bias correction "in reverse" when creating simulated dataset from regress...
I am developing 1000 simulation datasets where I add random noise to predictions from a regression model where the y-variable has been log-transformed to account for non-normality. … The noise is created from a normal distribution with mean equal to zero and SD equal to the residual standard error (RSE) from the regression model. …
