Greeting R Community, I'm trying to learn Logistic Regression on my own and am using An Introduction to Logistic Regression Analysis and Reporting (Peng, C., Lee, K., & Ingersoll, G. ,2002). This article uses a Score Test Stat as a measure of overall fit for a logistic regression model. The author calculates this statistic using SAS. I am looking for an [R] function that can compute

Hi There, There are 300 boy students and 100 girl students in a class. One interesting question is whether boy is smarter than girl or not. first given the exam with a difficulty level 1, the number of the student who got A is below 31 for boy, 10 for girl. Then we increase the difficulty level of the exam to level 2, the number of the student who got A is below 32 for boy, 10 for girl. We

Dear friends. Please see the program below and answer if it does simulate a population of 1.000.000 families, each with at max 20000 children (typical in Denmark, you know), constructed such that each family stops having children when more boys than girls are present ? Equal numbers of boys and girls are got in the population, according to the simulation, is that obvious ? ND <- NP <-

Let''s say I have three hypothetical MySQL tables: ? people, with columns id, gender, and source_id belongs_to :boys and :girls ? boys, with columns id and name has_many :people ? girls, with columns id and name has_many :people The gender column in people specifies which of the two source tables the source_id refers to. For example, if we have values: 1, boy, 1 in people,

I have two models, one model girl and one girl_photos (a file upload asset). The only code I have in models which describes the association is: For the girl => belongs_to :girl and has_attached_file :photo For the model girl_photos => has_many :girl_photos and accepts_nested_attributes_for :girl_photos I''ve tried to save as a nested attribute the photo, it saves the association

Hi, I am trying to test factory girl associations basically I have a user model and status model , what is supposed to happen is a user has many statuses and a status belongs to a user. I have tried to model this in factory girl as you can see in the files. When I try to execute the test I get Failure/Error: visit("/users/#{user.id}/statuses/#{status.id}")

How does one implement a likelihood-ratio test, to test whether the variances of the random effects differ between two groups of subjects? Suppose your data consist of repeated measures on subjects belonging to two groups, say boys and girls, and you are fitting a linear mixed-effects model for the response as a function of time. The within-subject errors (residuals) have the same variance in

Gents, My heads been out of the sql game for too long (or it''s simply too early). I''m trying to extend the acts_as_taggable plugin (note: not gem) so that you can specify a list of tags you''re interested in, and the plugin will return only those items that are tagged with *all* these tags. The plugin uses primarily two tables: tags, to keep all the various tag

Dear colleagues, I have another question, which, I think cannot be answered easily by the manual. What is the effect of including both nodefactor("Gender") and nodematch("Gender",diff=TRUE)) for the same variable in the model? Judging from the output (please see below), you cant have estimates for both for boys and girls forthe nodematch command, but I thought that the

Hello! I wonder if it''s possible to simulate Paperclip''s has_attached_file with Factory Girl and then test it with Rspec. I don''t get it to work.
