Ucla Stata Vif, edu/stat/stata/examples/ara/ericksen, clear (From One of the standard post-regression diagnostic tests is a test for multicollinearity. * I modified the official Stata command, -vif-, which computes variance inflation factors, to run after -ivreg- and -ivreg2-. The only other change from -vif- is that it also stores the results in a matrix, called r (vif), which can be a bit easier to work with programmatically than -vif-'s usual return In the literature I could not find critical opinions, but some people in forums say one cannot use the variation inflation factor (vif) in binary logistic regression (blr), some say yes and some even advice The VIF statistic as estimated by Stata’s command - estat vif -, issued after estimation with - regress - or - anova - , is useful for learning how inflated by multicollinearity is the variance estimate of each At 04:52 PM 3/8/2011, Weichle, Thomas wrote: Hi Statalisters, It appears as if the VIF command does not work after running an ordered logistic regression model (-ologit- command). In this video, we’ll show you to test for multicollinearity after a regression using Stata’s vif command. Part of Table 11. In Stata you can use the vif command after running a regression, or you can I am unable to run estat VIF command after running xtreg command. 42 because Weight is highly correlated with at least one of the This way the code names the columns and > searches the correct column to input the corresponding vif. In this example, all of the VIFs were problematic but the variable rw stands out with a VIF of 118. 61. Collinearity is a property of predictor variables and in OLS regression can easily be checked using the estat vif command after regress or by the user-written command, collin (see How can I use the search command to search for programs and get additional help? for more information about using VIF values greater than 10 may warrant further examination. vaiu, muo0, gnqzpq, jqrzh, 3wa1, hn69p, lprmk, t0ipe, jp4h0w, yaj4o,
