The same problem occurs if I use an alternative method of prediction: gllapred newvar, xb I have checked to see that I have the same variables in my dataset as in the estimated model. Variable names are in the correct case. The internal order of the variables in my second dataset is ...
(sample), xb Create newvar3, the default prediction for the first equation in a multiple-equation model predict newvar3, equation(#1) Same as above when y1 is the name of the first equation predict newvar3, equation(y1) Note: For a complete list of options available with predict after ...
MMQREG: Stata module to estimate quantile regressions via Method of Moments 17 XTCOINTREG: Stata module for panel data generalization of cointegration regression using fully modified ordinary least squares, dynamic ordinary least squares, and canonical correlation regression methods 18 RTMCI: Stata module...
Performance of the DELFIA Express sFlt-1/PlGF ratio <50 to rule-out pre-eclampsia within seven days was comparable to the PROGNOSIS study (Prediction of Short-Term Outcome in Pregnant Women with Suspected Preeclampsia Study), a prospective, multicentre, observational study of performance of assays ...
Post-resuscitation care after out-of-hospital cardiac arrest (OHCA) is challenging due to the threat of organ failure and difficult prognostication. Our aim was to examine whether urine biomarkers could give an early prediction of acute kidney injury (AKI) and outcome. Methods This was a prospect...
A two-sided p-value of < 0.05 indicated statistical significance. All analyses were performed using STATA14-MP (StataCorp LP, College Station, TX, USA) and R version 3.6.2 (R Foundation for Statistical Computing, Vienna, Austria). Ethical approval The ethics committee at Akita University...
directed acyclic graph of the assumptions underpinning the analytical model: the aim of covariate adjustment was to minimise confounding influences on the association between air pollution exposure and cognitive performance, rather than to construct a multivariable risk prediction model for cognitive outcome...
“opt-in” into the survey. This may have excluded respondents who are less motivated to take part in the survey. The survey was mostly promoted through online media and LGBT organisations which could affect the sample composition: groups with higher access to- and use of internet (young, ...
Dear all, This question is more related to research than to STATA. However, since many STATALISTER are familar with xtabond2-related research maybe somebody can help me. Comparing OLS and GMM after out-of-sample prediction for a dynamic model, my result is, that prediction based on OLS domi...
Ferritin had the best area under the curve (AUC), both for gastrointestinal cancer (0.746, CI: 0.691-0.794), and colorectal cancer (0.765, CI: 0.713-0.813), compared to the other parameters of iron deficiency. In the diagnosis of colorectal cancer, ferritin with ...
