The default is intpoints(7), which means that seven quadrature points are used for each level of random effects. If you’re dealing with, e. e. I usually use 30 quadrature points (intpoints). 35 trunc()—Roundtointeger Description Thesefunctionsconvertnonintegervaluestointegersbymovingtoward0,movingdown,movingup,or 4mepoisson—Multilevelmixed-effectsPoissonregression intmethod Description mvaghermite mean–varianceadaptiveGauss–Hermitequadrature;thedefault unlessacrossedrandom-effectsmodelisfit mcaghermite mode-curvatureadaptiveGauss–Hermitequadrature pcaghermite Pinheiro–Chaomode-curvatureadaptiveGauss–Hermite quadrature graphtwowayscatter—Twowayscatterplots5 jitteroptions Description jitter(#) perturblocationofpointjitterseed(#) random-numberseedforjitter()axischoiceoptions Refitting model intpoints() = 8 (output omitted ) Refitting model intpoints() = 16 (output omitted ) Quadrature check Fitted Comparison Comparison quadrature quadrature quadrature 12 points 8 points 16 points Log -3347. intpoints(#) speciﬁes the number of integration points to use for integration by quadrature. xtmelogit Estimation method Seconds 𝜷 𝝈𝜷 𝜷 𝜷 𝝈 True values 0. com eregress ﬁts models that we refer to as “extended linear regression models”. meoprobit is a convenience command for meglm with a mprobit—Multinomialprobitregression Description mprobitfitsamultinomialprobit(MNP)modelforacategoricaldependentvariablewithoutcomes thathavenonaturalordering intpoints(#) use # quadrature points to compute marginal predictions and empirical Bayes means iterate(#) set maximum number of iterations in computing statistics involving empirical Bayes estimators tolerance(#) set convergence tolerance for computing statistics involving empirical Bayes estimators Options for predict Main It appears that Stata will not generate irtgraphs after running an IRT model that uses pweights (svy:irt).

Hello Stata Experts, I am receiving a strange error when trying to run xttobit on a large set of panel data.
