While its relatively straightforward to convert this model object into a data frame and then plot manually using ggplot2, this is more work than we need to do here. Well also specify state+year fixed effects and explicitly cluster the standard errors at the state level (although this would be done by default). View. &Kqn}{*^2AkVAW Qbj9iN$7f~S r+;9hj&B? Box 7.4 Presenting the findings of a t-test on log-transformed data Figure 7.9 Code and Box 7.4 Since they vary in purpose, they plot data in different ways. * as of this writing, the coefficient matrix is unlabeled and so we can't do _b[] and _se[] . # skipping -1, the last one before treatment, # returns dataframe with dummy columns in place of the columns, # in the named argument, all other columns untouched, # Be sure not to include the minuses in the name, # get_dummies has a `drop_first` argument, but if we want to, # refer to a specific level, we should return all levels and, # Set our individual and time (index) for our data, # with the formula api: ()( | | | CSDN)2019-- Stata Stata 1. graph box . .
