...R help, I am trying to figure out the syntax for a three-level logistic model with a single random effect (intercept): Data Collected My data consist of three levels: level 1 is four setting for each student (setting nested within student), and each student is registered in one of 14 universities (students nested within university). More detailed: A. 2,479 students who have a dichotomous outcome, engaged in risk behavior (yes or no) in EACH of 4 different settings. Then I am using these settings as the level-1 units nested within the students, and the students as level-2 units. I also have three d...

Hi, R experts: I am asking for helps with manipulating this data: we have different groups: A,B, C, and so on. In each group, we have different students, for example, we have 6 students in A and 5 students in B. Each student gives a rating, which ranges from 1 to 3. We want to manipulate this data and add three more variables called as 1, as 2 and as 3. For example, in group A, for each student, we count the # of student before this student provid...

I want to use aggregate with the mean function on specific columns gender <- factor(c("m", "m", "f", "f", "m")) student <- c(0001, 0002, 0003, 0003, 0001) score <- c(50, 60, 70, 65, 60) basicSub <- data.frame(student, gender, score) basicSubMean <- aggregate(basicSub, by=list(basicSub$student), FUN=mean, na.rm=TRUE) This

Considering an object with several has_many :through => associations, what is the ''best'' way to handle validations? As an example: class Student < ActiveRecord::Base # some attrbutes like # :name # :grade # relationships has_many :students_assignment, :dependent => :destroy has_many :assignments, :through => :students_assignment has_many :students_class, :dependent => :destroy has_many :classes, :through => :students_class has_many :students_extracurricular_activity, :dependent => :destroy has_many :extracu...

...g to construct a matrix of a particular form. For the most part, developing the matrix is simple and is built as follows: vl.mat<-matrix(c(0,0,0,0,0,64,0,0,0,0,64,0,0,0,0,64),nc=4) Now to expand this matrix to be block-diagonal, I do the following: sample.size <- 100 # number of individual students I<- diag(sample.size) bd.mat<-kronecker(I,vl.mat) This creates a block-diagonal matrix with variances along the diagonal and covariances within-student to be zero (I am working with longitudinal student achievement data). However, across student, I want to have the correlation equal to 1 for...

Hi, We're encountering severe load problems associated with multiple smbd processes running per user. As an example below, this user has only five files open yet many smbd's running. Is there a reason for this occurring? I've been experimenting with file locking etc to try and get around it. Thanks Tim tim@hostname:~> smbstatus -u yunjeng -S INFO: Debug class all level = 1

Hi, I am very confused about an aspect of has_one and has_many relations, with regard to using the build method, and saving the belongs_to side. It''s a somewhat long post. so please bear with me :) First let''s consider the has_one scenario. Let''s say I have a student who must own exactly one car: class Student has_one(:car) end class Car belongs_to(:student)

Hi all, Last week I implemented samba a sa file server and domain controller for more than 150 computers (Win 2000 and XP). Everything is working just fine. However, computer science faculty wanted a share for each course in which students can upload their homework once done and teacher download them for correction. Yet, students can have the right to write on that share but not delete the work of other students. I did a test and works fine but students' work are delete-able by other users given the below share configuration: -...
