Hi all, Following up on Holger's email last week: Does anyone know if there exists a library that implements the sensitivity tests for hidden bias for matched pairs and unmatched groups as proposed in Rosenbaum's Observational Studies (2002: ch.4)? Thanks. Best, jens

Dear all, I am using the Instrumental Variable approach to estimate the causal effects of TWO endogenous variables in a Mendelian Randomization study. As long as point estimation is concerned, I have no problem: both "ivreg" in library "AER" and "tsls" in library "sem" do the job perfectly. The problems begin when I try to obtain confidence intervals for

I have a semantics question, I am reading Bowerman and O'Connell and they state that forecasting models fall into two categories, univariate and causal. My question is whether a time series regression model that relates the time series of interest to functions of time such as the day of the week or month of the year could be considered a causal model? thanks, spencer [[alternative HTML

I am doing a research on World Bank (WB) projects on developing countries. To do so, I am scraping their website in order to collect the data I am interested in. The structure of the webpage I want to scrape is the following: 1.

Thanks, Martin. I am trying this in Bengaluru, India, using R-studio. I tried downloading a single variable. It happened fast, in less than 5 seconds. I tried downloading six variables, it took much longer, but less than a minute. Tried eight variables and it did not download even in five minutes. My internet speed is well above 40Mbps. This should not take that long. It seems the process timed

Hi netters. Assume Y = {Y1,.....Yn} and X = {X1......Xm}, where Yi and Xi are random variables that can take on discrete values from V={0,1,2}. Each Yi in Y has some (0-k) parent variables in X, which means given the values of the parent variables (Xi0....Xik) the values of Yi is set. Yi = F(Xi0,...Xik), where F is a mapping function from parents to sons. Considering there are some noise in

Hi, I am using the sim1000G R package to simulate data for case/control study. I can not figure out how to manipulate this code to be able to generate 10% or 50% causal SNPs in R. This is whole code provided as example on GitHub: library(sim1000G) vcf_file = "region-chr4-357-ANK2.vcf.gz" #nvariants = 442, ss=1000 vcf = readVCF( vcf_file, maxNumberOfVariants = 442 ,min_maf =

Hi Berina, I'm not an expert on genetics. I haven't looked at the package. And I've only glanced at your question. So, this is probably not the best response. But as no one else has responded, here's some comments: (1) Have you checked if there's a function in the package to do what you want? The remainder of these questions assume that you have, and the answer is no. (2)

Hi, I am trying to create a googleVis motion chart with monthly data. When formatting the date column as a Date class variable, the plot as presented in the browser becomes considerably slower and very prone to crashing the browser. To illustrate this issue I have modified the WorldBank demo. ### objects from demo("WorldBank", package = "googleVis") M <-

Hello: I would like to sum every x columns of a dataframe for each row. For instance, if x is 10, then for dataframe df, this function will sum the first ten elements together and then the next ten: sapply(list(colnames(df)[1:10], colnames(df)[11:20]),function(x)apply( df[,x], 1, sum)) If the number of columns is quite large (1000's), then manually entering the list above is not practical.

There is some problem getting data with the WDI package. It gets data from World Development Indicators and other databases of The World Bank. I let the code run for several minutes and nothing happens. Sometimes it gives a time out message. I ran the same code last year and it worked. Any idea what the problem is and how to fix it? > dat1EU = WDI(indicator = c('NY.ADJ.NNAT.GN.ZS',

In the browser the link downloads immediately, in less than a second. I let the command run in R for five minutes, using R Studio. Nothing happened.
