This produces the finished graph that you can include in your papers: The visualization step for multiple regression is more difficult than for simple regression, because we now have two predictors. The null hypothesis is the same: no time-fixed effects needed. The relationship looks roughly linear, so we can proceed with the linear model. If the p-value is small, which indicates that we can reject the null hypothesis, then use time-fixed effects.

For this purpose, we consider the cumulative sum (CUSUM) control chart applied to different residuals of the beta regression model. In this case the p value is slightly larger than 0.05, it may still be better to use fixed effects models.
