Limitations ¶ Does not work with Weighting (yet). Stata Python; keep if df = df[] keep if a > 7: df = df[df['a'] > 7] drop if df = df[~()] where ~ is the logical negation operator in pandas and numpy (and bitwise negation for Python more generally). These pages are meant to help researchers use the correct techniques. 2, we can conclude that: "An increase of 20 mg/dl in LDL level has the same effect on the systolic blood pressure as aging 10 years".
