Hi everyone, First post here. I am looking for feedback on the results of my analysis of a sample proportion. My aim is to determine the probability of observing a sample proportion given a true proportion. In my example, my true proportion is 0.85 and my sample proportion is 0.82. My sample...

Hey all, similar to last year, I'm passing along the tracker for the top 4 statistical model trackers for the season. https://tinyurl.com/ybwyffu3 Good news is that they are all at 100% so far...

I am trying to deal with pseudoreplication of individuals in my study, and not quite sure how to handle it. I have been trying to account for individuals being sampled multiple times (twice usually) using a GLMM with individual ID as a random intercept. However, I think that the number of ID's...

Hi everyone, My first post! :-) I apologize for how long it will be, but please bear with me. I am looking for help in a topic related to Markov chain modeling with covariates. I have a decent knowledge of the underlying theory, but not exactly how to implement some aspects of it in practical...

Hi, I am learning basic programming with R, and I desperately need someone to write me a PSEUDO code and code for it please: Here's the situation "you have been sentenced to die tomorrow, but you're offered a way out... you get given 12 red balls and 12 blue balls together with two urns...

Hi guys, I have done my GLM model fitting on R and I was wondering if someone could help me with the following question : What is the probability for a male student to be admitted to department B? We have to use 'fit1' to answer the above question but I can't quite figure it out...

Hi, I have a longitudinal balanced tendon injury study with two treatment groups of horses (n=6/group) with 5 measurements over 6 mos measured on multiple MRI sequences. I have multiple questions with how I want to analyze this information, but my current question is the most pressing: Below...

I'm new to R and came over strictly to do a regression on a dataset with 28 variables and 60k entries (excel limits you to 16 variables). I watched some tutorials, read some guides, then wrote this script with the hope that I would easily get the results: mydata2 <-...

Hi all, Is there any pre-built function that can generate the following mapping: 1) Any 2 vectors, say... X1 = seq(-5,10, 0.1) X2 = X1^2 2) For a grade 2 mapping the output would be... out = [ X1 | X2 | X1^2 | X1.X2 | X2^2] (alternatively with one column X0 =1, but this can...

I've recently learned to output R figures and tables as latex code that I can then easily call into a document. Given the popularity of things like the r package knitr out there on the web, I'm curious if people here who write statistical documents, including slides, are users of the various...

Hello all, My name is Edwin R. Burgess, I am a Ph.D. candidate in biology at Northern Illinois University. My dissertation is being done on the effects of commonly used filth fly pesticides on parasitic wasp species used for biological control. Right now, I am doing binary mortality response...

Hi there, I am currently working on my thesis which is concerned with abnormality of differences between index scores on an intelligence test. An important factor here are the correlations between indexes. There are 4 indexes, hence 6 possible pairs. Correlations between indexes are provided...
