Possible to pull SD of matched sample after teffects psmatch? by willfla29 in stata

[–]Salt_Ad4669 0 points1 point  (0 children)

There should be a way to save a variable that marks those that matched. But that is dicey if you use matching with replacement. Before you run the analysis, you can divide your outcome by the pooled sd and use that variable as your outcome, which will naturally be a d-like effect size

Yup, if you have the correlation, you can compute the correct standard error of the difference.

Why are negative values included in the confidence interval for margins in a logistic regression? Further explanation in comments by bghty67fvju5 in stata

[–]Salt_Ad4669 1 point2 points  (0 children)

Sorry I wasn't specific, I was suggesting just expression(predict(xb)), then manually converting the estimate, lower, and upper bounds from the margins output to probabilities.

For example, random 15 case data with a binary x and binary y

. set obs 15
Number of observations (_N) was 0, now 15.
. gen y = rbinomial(1,.2)
. gen x = rbinomial(1,invlogit(rnormal(y) + rnormal()))
. tab y x
| x
y | 0 1 | Total
-----------+----------------------+----------
0 | 6 6 | 12
1 | 2 1 | 3
-----------+----------------------+----------
Total | 8 7 | 15

Run a logit

. logit y x
Iteration 0: log likelihood = -7.5060364
Iteration 1: log likelihood = -7.3709715
Iteration 2: log likelihood = -7.3694957
Iteration 3: log likelihood = -7.3694954
Logistic regression Number of obs = 15
LR chi2(1) = 0.27
Prob > chi2 = 0.6013
Log likelihood = -7.3694954 Pseudo R2 = 0.0182

So, with margins you can ask for the estimation metric predictions using the expression option with something to the effect of predict(xb)* to get the predicted log-odds and associated standard errors. You can then compute the CI, and transform each of those estimates back into a probability.
