similar to: R package for scorecard development

Hi all, I have 2 models with a standard 1 to many relationship. I''m also using REST on the two models and have added the appropriate code to the routes.rb file. scorecard.rb: class Scorecard < ActiveRecord::Base has_many :attributes end attribute.rb: class Attribute < ActiveRecord::Base belongs_to :scorecard end routes.rb: map.resources :scorecards do |scorecard|

Hello, I have a CSV file with region codes listed in a column. E.g. 'AS' for Asia, 'AU' for Australia and 'NA' North America. However, the data frame created using read.csv shows <NA> where the string variable should have had the value 'NA'. How can I input the value 'NA' present in a column in a CSV file without R changing it to missing? Thanks

Hello all, I am looking for theories and statistical analyses where the defaults employed in R and SAS are different. As a result, the outputs under the defaults should (at least slightly) differ for the same input. Could anyone kindly point any such instance? Thanks Nikhil

Apologies if this is in the archive - did look but couldn't find it. Does anyone have any experience of migrating from CommunigatePro to Dovecot? We currently run CGP 5.3.4, supporting a small system (20 or so users, one domain). We've been using it for years, and have a mixed bag of MailDir and mbox folders accessed via IMAP clients. Some users have large mail accounts (15GB total).

I don''t have a class by the name of "ReviewersScoreCard", yet my many to many configuration looks as follows.

Hi! I am working on scorecard model and I have arrived at the regression equation. I have used logistic regression using R. My question is how do I validate this model? I do have hold out sample of 5000 customers. Please guide me. Problem is I had never used Logistic regression earlier neither I am used to credit scoring models. Thanks in advance Maithili

Hello All, How do I save the output of the R console and the graphic output to the same PDF file and append these to each other? I need to have a frequency table and a corresponding graph, one below the other in a file. I have tried with sending the cross table to the graph window using 'textplot' and then saving the graphic output. However, the table does not look nice in the graph

Hi Everybody! I must start with a declaration that I am a sparse user of R. I am creating a credit scorecard using a dataset which has a variable depicting actual credit history (good/bad) and 41 other variables of yes/no type. The procedure I am asked to follow is to use a penalized logistic procedure for variable selection. I have located the package "glmnet" which gives the complete

Hi, is there an easy way to get the calculated weights in a regression equation? for e.g. if my model has 2 variables 1 and 2 with coefficient .05 and .6 how can I get the computed values for a test dataset for each coefficient? data var1,var2 10,100 so I want to get .5, 60 back in a vector. This is a one row example but I would want to get a matrix of multiplied out coefficients

Hello, I try to find a way to handle SSH connections differently depending if it comes from a 'trusted" computer or from an unknown computer (for instance giving access to a shell versus allowing only scp/sftp in a chrooted environment). Using the IP address is not a solution since a trusted computer can be a laptop that is connected somewhere on Internet. One solution could be to use

Hello! This is my first time trying to run dovecot so maybe I've overlooked something, but I'm having a hard time running dovecot. First of all, it's worth noting that I'm trying to run dovecot on an embedded platform: the target architecture is mipsel; I have patches for the 2.4.18 kernel with special support for the board so I'm still using the 2.4.18 kernel.
