Violation of sample independence in Pearson's product-moment correlation
...assumption of sample independence for Pearson's test, and I should have had only 7 points, which would reflect the means of my two variables for each individual animal across 10 days. Is this appropriate or is there a means of accounting for repeated sampling with a correlation test? - Justin Montemarano Graduate Student Kent State University - Biological Sciences http://www.montegraphia.com [[alternative HTML version deleted]]

coxph() command design and data setup
...block? Additionally, I have a frequency column in data.table that indicates how many of a particular observation occurred in each row. Is it appropriate to assign this column as a weigh argument in cosph? If so, how is that done? I can send sample data if necessary. Thanks for any help!

coxme() random effect syntax
...+ SUBSZ + CFSZCL:SUBSZ, data = data.table) However, I would like to add rock movement (BEDLOAD) as a random co-variate, which is not possible with the coxph() function. Is it possible to do so with coxme() in the kinship package? If so, what is the proper syntax? Thanks for any help. Justin Montemarano

Testing treatment effects on exponential decay models
...above model for each treatment and approximate k, but I would like to examine treatment effects on these fits as I might using glm(). If I can get passed this hurdle, I may also inquire about adding a random effect as well. If it helps, I can post a subset of data.

coxph models for insects
...f 4 observations or insects, all within 1 treatment. The block variable is room, where each room contains ~40 chambers each of which has been randomly assigned a treatment. I believe that I have chamber %in% treatment right in representing my data, but how do I account for room as a block? Justin Montemarano

Find the first values in vector
Hi ! I have a vector: vec= TRUE TRUE TRUE TRUE FALSE FALSE FALSE FALSE TRUE TRUE FALSE and I'm looking for a method which let me get only the first values equal TRUE from this vector. It means that I want to get a vector: vec_out = TRUE TRUE TRUE TRUE or posictions values = TRUE: vec_out = 1,2,3,4 -- View this message in context:
