Question

Before 2013, string functions in this software could only return at most 244 bytes, so things would accidentally get truncated all the time. When using this software, it’s recommended to set varabbrev (“var-abbrev”) off because, by default, users can shorten variable names to any unambiguous prefix. Boston College hosts an archive of user-contributed programs (-5[1])for this software that can be installed with its ssc command. This software has two custom languages: the matrix-oriented mata and the command-based ado, which uses commands like “twoway” for a scatterplot. Version 18 of this software introduced a new default graph format with horizontal y-axis labels (-5[1])and added support for heterogeneous (*) difference-in-differences models. Whether to learn R or this software (10[1])is a common (10[1])dilemma for economics students. (-5[1])For 10 points, name this program that, like SAS and SPSS, is a proprietary statistical software. ■END■ (10[1]0[2])
