Summary, in English

You want to run an experiment where you anticipate finding a treatment effect.
How large should your sample size be to have a reasonable chance of detecting
significant results? In this manuscript, I present and explain the Stata code I use to
address this question. The code uses simulations to conduct power analyses,
offering a flexible alternative to the commonly used analytical tools. Unlike
traditional methods, this approach can accommodate any experimental design and
statistical test that Stata supports. The code is straightforward, user-friendly, and
can be used effectively with minimal coding experience.
