Hi, I found a discrepancy between results in R and Stata for a factor analysis with a promax rotation. For Stata: . *rotate, factor(2) promax* (promax rotation) Rotated Factor Loadings Variable | 1 2 Uniqueness -------------+-------------------------------- pfq_amanag...

Hello I would like to develop the use of R. Trying R and more particulary the cox model, I am surprised by discrepancies between results with stata and R for a cox model With the same data base, I get a hazard ratio (4.82) that is not the same obtained with stata (4.52) You will find attached the file leukemia.dta I used (Stata) Here are the codes for R library(foreign)

Hello, I am looking for an explanation and/or fix for a discrepancy in the behaviour of the R lm.influence() function [ version R 1.5.0 (2002-04-29) ] and the same function in Splus [ Splus version 5.1 release 1, running on SGI IRIX 6.2]. The discrepancy is of concern because I am migrating some Splus scripts to R and need to ensure consistency of results. Speci...

...plied to RxC tables which are larger than 2x2. One can summarise a strategy for the test as 1) For each table compatible with the margins of the observed table, compute the probability of this table conditional on the marginal totals. 2) Rank the possible tables in order of a measure of discrepancy between the table and the null hypothesis of "no association". 3) Locate the observed table, and compute the sum of the probabilties, computed in (1), for this table and more "extreme" tables in the sense of the ranking in (2). The question is: what "measure o...

Hi! I want to create a discrepancy matrix. I have got a data.frame Q: number colour date 2 343 b 1503 3 678 g 1701 4 347 b 1904 5 345 b 2001 6 123 g 1809 Now i want to create a matrix, whose entries are the t...

Hi, I would liek to ask the list if any one can explain why there should be a discrepency in the directory sizes that are displayed when I use explorer on Windows. This has been reported to me by a user, I have never seen this before as I dont use windows if I can help it :-)... When I slect properties of a directory it has two enties Size and Size on disk As an example size says 33 bytes, size

Dear R community, I am trying to resolve a discrepancy between the way SPSS and R handle 2-way, repeated measures ANOVA. An experiment was performed in which samples were drawn before and after treatment of four groups of subjects (control and disease states 1, 2 and 3). Each group contained five subjects. An experimental measurement was perform...

Hello. I see many discrepancies in config.h file generated by CMake and autoheader. Most of them are following: In autofoo-generated config: > /* Define to 1 if you have the `<name>' function. */ > #define HAVE_<name> 1 > but in CMake-generated: > #undef HAVE_<name> > This happens because in config.h.cmake (config.h.in analog) these functions just are not

...re could create problems. Of course for classes that should inherit the implicit type, it can be explicitly added to the end of the class() vector by its constructor.

Is there any way to _test_ if a given sequence is a low-discrepancy sequence? Or, equivalently, is there any way to measure the "discrepancy" of a sequence? WTIW, ... http://en.wikipedia.org/wiki/Low-discrepancy_sequence ... doesn't look like something implementation-friendly :-) Alberto Monteiro PS: low discrepany sequences are easily generated...

I have been using R and SAS from past 6 months and i found a interesting thing while doing PLS in R and SAS is that when we use NO SCALE option in SAS and scale=FALSE in R , we see the estimates are matching but if we use scaling option in SAS and R the estimates differ to greater extent , you can try with any data set we will get very different estimates while using the scaling option. can any

In the course of exploring response prediction, I stumbled upon a small discrepancy between the CIs produced by predict.lm() and all.effects() require(mlmRev) require(effects) hsb.lm <- lm(mAch ~ minrty * sector, Hsb82) hsb.new <- data.frame( minrty = rep(c('No', 'Yes'), 2), sector = rep(c('Public', 'Catholic'), each = 2)) hsb.eff...

...or couples 6-8 are wildly different between the coef() and intervals() output. Granted, fitting an intercept, slope, and quadratic to 4 data points doesn't leave much for an error term, but it seems like the intercept coefficients ought to be the same. If the quadratic is dropped, there is no discrepancy between coef() and intevals(), so perhaps this is related to the complexity of the model vs. sparseness of data? Any insights appreciated (data below). Dave -- Dave Atkins, PhD datkins at u.washington.edu tmp.df <- data.frame(id = as.factor(rep(1:8, each=8)), sex = fact...

In addition, signed zeroes only exist for floating point numbers - the bit patterns for as.integer(0) and as.integer(-0) are identical.

...`u` vector; `s4` is the closest double precision to this exact sum. Looking at the C source code for sum() will show you that it makes some extra efforts to get a more accurate sum than your simple version.

...e model that generates it. Thus, the location of information I'm wanting to extract from the file is not in a fixed position (i.e. it does not always appears in a predictable location, like line 1000, or 2000, etc.). Rather, the desired values always follow a specific phrase: " PERCENT DISCREPANCY =" One approach I took was the following: library(R.utils) txt_con<-file(description="D:/MCR_BeoPEST - Copy/MCR.out",open="r") #The above will need to be altered if one desires to test code on the attached txt file, which will run much quicker system.time(num_lines&lt...
