The logit of the propensity score
Splet29. nov. 2024 · And so, because I told it to match on the logit propensity score, a 0.2 means 0.2 times the standard deviation of logit of the propensity score. So it's- the caliper isnt't actually 0.2, it's 0.2 times standard deviation of logit to the propensity score. All the other steps are the same. SpletTo explain further, IF propensity score matching was used in a randomized experiment comparing two groups, then the propensity score for each participant in the study would be 0.50. This is because each participant would be randomly assigned to either the treatment or the control group with a 50% probability. In study designs where there is no
The logit of the propensity score
Did you know?
SpletOn the standardized scale, the caliper is interpreted in standard deviations of the propensity score distribution. 'standardized logit' is similar, except that the propensity score is transformed to the logit scale because the PS is more likely to be normally distributed on that scale (Austin, 2011). maxRatio Splet18. jul. 2024 · For the logit Propensity Score Matching (PSM) dataset, we can see that. The estimated causal impact is 10.35. The 95 percent confidence interval is 10.00 to 10.70.

It is the logit from the logistic regression. The higher the score, the more likely one is assigned (or chose) the NEW treatment.
SpletThe remaining 933 patients were included in the final analysis: 676 with diastolic hypotension, with a median (IQR) duration of DBP <60 mmHg for 45 (25–65) min, and 257 without diastolic hypotension. After propensity score matching, 246 patients remained in each group (Table 1, Figure 1).
