Without <code>fixest</code>, PyFixest likely wouldn’t exist - or at the very least, it would look very different. Most importantly, <code>fixest</code> has shaped our understanding of what a user-friendly regression package should look like and what functionality it should offer.</p>

 <p>PyFixest is tested against fixest via <strong>rpy2</strong> to ensure numerical equivalence (usually <code>rtol = 1e-08</code>, <code>atol = 1e-08</code>) for coefficients, standard errors, t-statistics, p-values, confidence intervals, etc for OLS, IV, Poisson, and GLM models.</p>
