Thank you both very much ! This helped me a lot. Best, Holger -- View this message in context: http://r.789695.n4.nabble.com/Hausman-Test-tp3220016p3220123.html Sent from the R help mailing list archive at Nabble.com.
Dear Arne, this looks promising! Thank you very much. Best, Holger -- View this message in context: http://r.789695.n4.nabble.com/Hausman-test-for-endogeneity-tp2969522p2970564.html Sent from the R help mailing list archive at Nabble.com.
Wow, this was fast and helpful! Thank you very much. Best, Holger -- View this message in context: http://r.789695.n4.nabble.com/Simulating-correlations-with-varying-sample-sizes-tp3526231p3526288.html Sent from the R help mailing list archive at...
Dear folks, can anybody point me in the right direction on how to conduct a hausman test for endogeneity in simultanous equation models? Best, Holger -- View this message in context: http://r.789695.n4.nabble.com/Hausman-test-for-endogeneity...
Hi Wolfgang that's good news. One further small follow-up question: When I conduct multiple comparisons via the relevel-command: should I adjust the p-value? Thanks in advance, Holger -- View this message in context: http://r.789695.n4...
Hi folks, I tried for the first time hclust. Unfortunately, with missing data in my data file, it doesn't seem to work. I found no information about how to consider missing data. Omission of all missings is not really...
Dear Liviu, thank you very much. After inspecting the options, I *guess* that systemfit is what I need. However, I absolutely don't understand how it works. I searched long for a detailed documentation (beyond the rather cryptic standard documentation...
Hi there, say, I have 100 matrices (m1,m2,...,m100) which I want to combine in a list. The list, thus, shall contain the matrices as components. Is it necessary to mention all 100 matrices in the list() command? I...
Hi folks, I conducted a hierarchical cluster analysis. As I wanted to illustrate the result, I created a dendrogram with the code plot(as.dendrogram(fit),sub="",xlab="",ylab="Heterogeneity",nodePar = list(lab.cex=.5,pch=NA,xlab="")) However, the...
Hello folks, many multivariate anayses (e.g., structural equation modeling) require multivariate normal distributions. Real data, however, most often significantly depart from the multinormal distribution. Some researchers (e.g., Yuan et al., 2000) have proposed a multivariate transformation of the...
Hi there, I would like to conduct a mixture regression analysis with the flexmix Package. Was just playing around with the function stepFlexmix() and did not get a foot into the door. When I run the stepFlexmix-function, I get...
Hi, can anybody tell me how the Hausman test for endogenty works? I have a simulated model with three correlated predictors (X1-X3). I also have an instrument W for X1 Now I want to test for endogeneity of X1...
Hi there, when using the metafor package for testing mixed effects models with categorical moderators, I get a regression table reporting betas. These betas are mean differences between a certain category in the effect size to the reference category (intercept...
Hi there, I would like to draw 10 correlations from a bivariate population - but every draw should be done with a different sample size. I thought I could to this with a loop: r=numeric(10) #Goal vector N = c...
Hi there, when conducting a multidimensional scaling analysis, it is possible to do this on a correlation matrix? I calculated a dissimilarity matrix by substracting the corr.matrix from 1. Then I calculated the distance matrix with d <- dist(dissimilarity...

Dear Achim, thank you very much. One follow up question. The Hausman-test always gives me a p-value of 1 - no matter how small the statistic is. I now generated orthogonal regressors (X1-X3) and the test gives me...
Wow, thank you so much! Where can I learn such creative approaches? Best, Holger Romain Francois-2 wrote: > > Hollix wrote: >> Hi there, >> >> say, I have 100 matrices (m1,m2,...,m100) which I want to combine in a >> list. >> The list...
Hi folks, I created a subset of a dataframe (i.e., selected only men): subdata <- subset(data,data$gender==1) After a residual diagnostic of a regression analysis, I detected three outliers: linmod <- lm(y ~ x, data=subdata) plot(linmod...
Hi Guys, thank you all for you comments. Actually, I had a typo and you'r right that it should be "subdata[-c(11,22,33) , ]" However, this does not work well either. I think, I know the reason: In...
