Hi everyone, I emailed yesterday thinking I had a problem with reading matrix information as numerical output into epiR. After working on the data frame today, I realise it's a problem with the data itself rather than the syntax.

Hallo! Does anybody know how to calculate a sample size estimation for proportions with continuity correction? ? I only found EpiR which seems to calculate without continuity correction: library(epiR) epi.studysize(treat = .65, control = .50, n = NA, sigma = NA, power = 0.80, r = 1, conf.level = 0.95, sided.test = 2, method = "cohort") $n [1] 340 Thanks!

Hi all, I want to know how to perform the test Breslow-Day test for homogeneity of odds ratios (OR) stratified for svytable. This test is obtained with the following code: epi.2by2 (dat = daty, method = "case.control" conf.level = 0.95, units = 100, homogeneity = "breslow.day", verbose = TRUE) where "daty" is the object type table svytable consider it, but

This is a really simple question, I'm sure,but I can't make EpiR work! I keep getting the following: > epi.2by2(47, 263483, 282, 935028, method="cohort.time", conf.level=0.95) Error in epi.2by2(47, 263483, 282, 935028, method = "cohort.time", conf.level = 0.95) : unused argument(s) (935028) and I really don't know why!. Any idea...

I would like to compare the incidence rates of three groups. They are supposed to have different risks so I would like to test whether there is a increasing trend in the incidence rates. Does R or any packages provide a trend test for incidence rates? I checked epiR and epitools. It seems they do not have this function. Thank you for the help. -- View this message in context: http://r.789695.n4.nabble.com/trend-in-incidence-rate-tp4634591.html Sent from the R help mailing list archive at Nabble.com.

Hi. I have data which i would want to assess the degree of agreement between two assays, e.g., to evaluate reproducibility or for inter-rater reliability. I have used the Pearson product-moment correlation coefficient. It looks good ranginging between 0.90 to 0.998. Though this looks good. I am told the Concordance correlation coefficient will give a better picture of how reproducible the assay

...am, I hope this email finds you well. I am writing to inquire about the specific R packages that would best suit our academic research project, which involves analyses in various fields. We are particularly interested in the following areas: Epidemiology Analysis: We are aware that packages like epiR, survival, and epitools exist for epidemiological analysis. Could you please confirm which of these (or others) would be most suitable for our needs? Dietary Intake/Analysis: We are considering packages like foodfreq and Dietary for dietary intake analysis. Are these the best options, or do you rec...

Hi everybody, I'm trying to create a numerical data frame on which to perform PRCC. So far I have created a data frame that consists of function/vector output that displays in numerical form, but when I try and run PRCC (from epiR package) I get the following error message: "Error in solve.default(C) : Lapack routine dgesv: system is exactly singular" It appears this is because the data frame is passing character strings rather than the numerical data to R. An example of my original data frame minmaxfunc is a...

...a two level factor. Not every level is present in each block. Each block has a Status attribute with two levels: medium (9 blocks) or good (5 blocks). Besides the overall ratio, we would like the estimate the ratio per Status. The samplesize per stratum was calculated with epi.stratasize() from the epiR package. The population size in the 21 strata ranges from 1 to 1158. The sample size ranges from 0 in the blocks with very few polygons (<20), 1 in blocks with a low number of polygon (20 - 50) and up to 25 polygons in the largest strata. Does the syntax below represents the data structure abov...
