similar to: Using mfx to create marginal effects

I have upgraded R (from 3.6 to 4.0) and RStudio (from 1.1 to 1.2.5) a few days ago, and Ubuntu from 18.04 to 20.04 yesterday. Since then, R sometimes never terminates when executing certain commands: ivreg (from package AER), summary (of a logit regression) and logitmfx (from package mfx). Sometimes these commands run fine, but most of the time I have to kill the process because R won't

When I try to run the program Knytt Stories, I get an error window that says: "Cannot Load DirectoryPacker.mfx. This object might need an external program or library not yet installed." Wine helper says, Code: err:module:import_dll Library MSVCP60.dll (which is needed by L"C:\\windows\\temp\\mrt188.tmp\\DirectoryPacker.mfx") not found fixme:heap:RtlCompactHeap (0x110000,

Dear all, I have two questions that are almost completely related to how to do things in R. I am running an ordinal probit regression analysis in R. The dependent variable has three levels (0=no action; 1=warning; 2=sanction). I use the lrm command in the rms package: print( res1<- lrm(Y ~ x1+x2+x3+x4+x5+x6, y=TRUE, x=TRUE, data=mydata)) I simply couldn't make any sense of the

I have a question regarding calculating marginal effects (change in the probability due to a one unit change in x) for a probit or for that matter any discrete choice model. Does R have a function that will essentially do this: dE[y|x] ------- = f(x'beta)*beta dx Stata has a command called "mfx" that calculates the marginal effects at the mean (of the x

Dear all, I want to backtest my Value at Risk output using the VaRTest() function in the rugarch package. I do not understand if the numeric vector of VaR which needs to be calculated is in negative or positive terms. Usually VaR is expressed in positive terms. Do I have to use positive values for VaR in the VaRTest() formula? Thanks for your help. [[alternative HTML version deleted]]

Dear R users, I am trying to generate a 3D surface plot given the inflator formula in the attached file. Now, I want to create a 3D plot showing how Delta changes with the values of Abs(B) and sigma. The other variables in the formula are constant. Delta is calculated daily therefore the subscript t which denotes the day. I have used different functions and different packages but I get either

Has anyone gotten centos 4 to print on an officejet 7310? I have tried jetdirect with pcl and postcript no go... I have tried smb but it does seem to be browsable as its not listed and when I specify I enter the IP address for server and I dont know what the share is. Windows XP connects and prints fine. THanks, Jerry

Dear R-help, my aim is to fit a constrained 2 component gamma mixture using mix within package mixdist. The constraints being fixing both of the means and both of the sigmas. Thus the only unconstrained parameter I wish to fit is pi the proportions of the mixtures. This is the code I used: PP2Pars<-data.frame(c(0.23,0.77), c(9.174,29.54), c(9.983,12.369));

Dear ALL, I'm trying to figure out what the percentage effects are in a logistic regression. To be more clear, I'm not interested in the effect on y of a 1-unit increase in x, but on the percentage effect on y of a 1% increase in x (in economics this is also often called an "elasticity"). For example, if my independent variables are in logs, the betas can be directly

Hello list. I'm trying to rebuild the 2.6.9.67.0.20.EL kernel, but it fails even without modifications. How did I try it? Created a (non-root) build environment (not a mock ) Installed the kernel.scr.rpm and did a rpmbuild -ba --target=`uname -m` kernel-2.6.spec 2> prep-err.log | tee prep-out.log The build failed at the end: Processing files: kernel-xenU-devel-2.6.9-67.0.20.EL Checking
