I''ve added a drop-down list of first and last names of borrowers to a form. How do I sort them by LastName, FirstName in the drop-down? I''m using code based on the cookbook example: <select name="borrower[borrower_id]"> <% @borrowers.each do |borrower| %> <option value="<%= borrower.id %>"> <%= borrower.FirstName <<

Hello, I'm interested in correcting for and measuring unobserved heterogeneity ("missing variables") using R. In particular, I'm searching for a simple way to measure the amount of unobserved heterogeneity remaining in a series of increasingly complex models (adding additional variables to each new model) on the same data. I have a static database of 400,000 or

I have a loans table and a payments table. Each loan has_many payments. So far no problem. Now, the payments table has a payment_number field, and each payment has a payment_number unique within that loan. For example, Loan A can have payment_numbers 0, 1, and 2 and Loan B can have payment_numbers 0, 1, 2, and 3 (but only one of each payment_number). I can enforce this with a unique index in

Agile Web Development with Rails doesn''t seem to have NULL in the index [or my eyes have failed me again], and web searching turns up lots of SQL statements containing NOT NULL. I have a table of loans, and I want to record when something was loaned and returned. The loan date can''t be null, or there''d be no entry in the table. The return date must be something

Hi All I found survfit function was very slow for a large dataset and I am looking for an alternative way to quickly get the predicted survival probabilities. My historical data set is a pool of loans with monthly observed default status for 24 months. I would like to fit the proportional hazard model with time varying covariate such as unemployment rates and time constant variables at loan

Hola, ¿qué tal? Tengo un df relativamente chiquito: > dim(loans) [1] 15172 22 > object.size(loans) 7488144 bytes Sin embargo, empresas <- split(loans, loans$number_id) length(empresas) #8748 object.size(empresas) # 50643907728 bytes Es decir, el objeto resultante de partir un df de 15000 filas en 8700 dfs ocupa 5GB. ¿Alguna idea de por qué ocurre esto?

Help! I have a new/create process that works fine in the actual app. But when I test I always get a failure in the test_create section.

Interesante... y preocupante. No propuso alguien, no hace mucho, reescribir R desde el principio por este tipo de cosas?

Hola, ¿qué tal? Al final he descubierto el motivo del problema. Cierto que esperaba cierto nivel de _overhead_, pero nunca tantísimo. Por mucho _overhead_ que haya, no se pasa de 7MB a 5GB. El problema era que (a pesar de mi opción stringsAsFactors = F) los niveles de los factores se copiaban íntegros en cada una de las columnas de tipo factor de cada una de las tablas resultantes. Aunque no se

Hello! Given is an Excel-Sheet with actually 11,000 rows and 9 columns. I want to work with the data in R. The contents are similar to my following example. I have a list with ID-number, personal name and two kinds of loan-values. I want to aggregate the list, that for each person only one row remains and where the loan-values are added. First I tried some commands with tapply but had no

I wonder if someone out there could loan me a peek at their sip.conf? I have conflicting advice, for instance, about whether or not to use "nat=1" and also whether or not the ATA should be registering with the instance of asterisk it is going to be using to dial out. Thanks in advance. B.

Today, WINE has a distributed database of applications owned by the users of WINE. Practically, this solution is probably the only legal way to proceed unless the WINE project literally funds the purchase of every application for Windows. * Maybe, an owner of a specific program can loan the masters of their Windows programs to the WINE project with the guarantee that they'll be returned within

Hi, I am working on fitting a proportional hazard model to predict the probability of default for mortgage loans. I have a question regarding survfit function. My historical data set is a pool of loans with monthly observed default status for the next 24 months. The data is left truncated (delayed entry to observation window after the loan is opened) and right censored. I would like to

I'm in Europe (at least until the 23rd...) so let me know your address. My motivation is to get them working reliably under Fedora 23 x86 to drive a Dell UP2414Q 4k monitor, where currently my father's PC is experiencing regular freezes. So if you would like the loan of a UP2414Q monitor to go with the cards, let me know too. (The UP2414Q is an interesting monitor to drive since it

Hola, ¿qué tal? Lo que quieres es un "debugger visual" (como el de muchos IDEs, incluyendo Netbeans y Eclipse) para R, como el de Revolution, http://www.youtube.com/watch?feature=player_embedded&v=7shLKEINM9A#! Pues sí, efectivamente, existe, pero solo con la versión de Revolutions de R. Y verás también que está basado en el "debugger" tradicional de R, que permite
