If you are new to item response theory or to the item response theory features in Stata, we encourage you to read [IRT] irt first. Example 1: Logistic regression test for uniform and nonuniform DIF To illustrate logistic regression DIF analysis, we use an abridged version of the mathematics...
Stata probit and logistic regression (logit) commands are under Statistics → Binary Outcomes Inference and Measures of Fit Standard errors, hypothesis tests, and confidence intervals are exactly as in OLS, but they refer to the coefficients and must ...
Using Stata features to interpret and visualize regression results with examples for binary models. Isabel Canette Senior Statistician StataCorp LP 2014 Spanish Stata Users Group meeting Barcelona, October 23, 2014 Introduction The best way to present results depends on the readers we are addressing. ...

is the pdf and Φ(.) the cdf of the standard normal distribution. In the logit model, the transformation function F is the logistic func- tion. The response probabilities are then P(y i = 1|x i ) = e x i β 1 +e x i β = 1 1 +e −x i β Figure 1 shows the ...
First, we estimate the regression coefficients of a sim- ple logistic regression in which the repeated observa- tions within the same individual are assumed to be inde- pendent (i.e., ignoring the correlation). We then obtain the slope estimates and standard error estimates based on the GEE...
This multiple imputation strategy is implemented using MI, MIANALYZE, GENMOD, and NLMIXED procedures in SAS. 2.4.2. Random-effects logistic regression Compared to the predictive model using standard logistic regression method, we assume the binary outcome is modeled by the random-effects logistic ...
Multivariate logistic regression models assessing associations between mental health symptoms and gender affirmation for all youth are depicted in Table 4. Higher levels of parental acceptance were associated with lower odds of depression symptoms (adjusted odds ratio (aOR), 0.91; 95% CI, 0.87–0.96)...
