Muy buenas, quiero calcular correlaciones de Pearson entre dos variables (a,b) teniendo en cuenta una tercera (c). Para ello estoy usando una función llamada "pcor.test" (http://www.yilab.gatech.edu/pcor.html), que en realidad no está en ningún paquete de R, que yo sepa. ¿Alguien conoce una función similar en alguna librería de R? Por otro lado, para ver si me cuadraban los resultados,

  Buenos días:   Antes de nada, disculpadme por ocuparos tiempo en el día del trabajador...   Hace unos días o semanas pregunté acerca de cómo calcular la contribución parcial de una componente al Multiple R-squared que devuelve lm.   En su momento Carlos Ortega me informó acerca de varias opciones (ols, regsubsets,... e incluso me referenció un libro). El caso es que por ninguna de las vías he

...) el modelado lo llevo a cabo del siguiente modo: lm( y ~ X1 + X2) Para el caso de componentes múltiples: Y = M + ?Aj * cos(2*pi*t/Tj + phij) + error Si Tj conocidos: Y = M + ?(betaj*X1j + gammaj * X2j) + error Modelado: y ~ x1tot+ x2tot, donde los xtot (x totales) resultan de la suma de los parciales (donde cada parcial corresponde a un Tj). Sin embargo, en el caso del modelo generalizado (componente cuadrática, cúbica, etc.): Y = M + alfa1*t + alfa2*t2 + (?Aj * cos(2*pi*t/Tj + phij)) + error ¿Qué facilidades ofrece R para el estudio de este modelo?. Se hace manualmente?. Gracias. Un salu...

Hola: A ver si me podéis ayudar que estoy atascado... Necesito contar los subcasos de la columna 2 de un dataframe respecto a los casos de la columna 1. Es decir, tengo un data.frame a<-c(rep(c('a','b','c','b','c'),3),'b') b<-c(rep(c('x','y','z','w'),4)) c<-c(rep(c(1,1,0,0),4))

Hi Johannes, Sorry about the failing tests. I completely forgot about running all of them, I only ran the tests for the openmp ipo transforms. I found the GH issue in cache. I can post it here if you want. I analyzed these runtime calls, __tgt_target_teams_[nowait]. What I don't understand about the problem we want to solve (splitting the memory transfer into issue and wait and legally

Hi Johannes, Yes, I'm highly interested, I already started. It would be nice if you post the details again. I didn't take note of them, I was always looking at the issue in GH. The problem I'm facing right now is this: The first task is identifying OpenMP API calls referred to device memory allocation. I first understood how the compiler driver orchestrates the process of offloading

Ahhh I understand. So I believe the project you posted is still opened. Do you any advice on the question I posted before?. Thank you. On 22/03/20 1:26 p. m., Doerfert, Johannes wrote: > I did not.

Hi Johannes, I've been thinking on how to implement a solution for the problem and I have some questions: 1. You mention in the problem description that the current asynchronous functions can be used, and probably modified. The problem is that those runtime functions with _nowait at the end are not asynchronous. Looking at their implementations, they just wait for other tasks is there

Hi Johannes, In order to create the testcases with the FIXMEs showing how it should look after the transformation, I've been trying to come up with a way of splitting the runtime call __tgt_target_teams based on Silei's recent patch D77005. I like the idea of using its asynchronous version __tgt_target_teams_nowait, but I think we would have to modify it, either to return the

Hi there Johannes!, I was checking out the issue (about latency hiding when transferring memory from host to device) you posted about a week ago, but it's not there anymore. Did you remove it?.

Hi Hamilton, I personally don't believe the effort to make the IR "parallelism-aware" is worth it right now. What I propose is something else, see for example https://youtu.be/zfiHaPaoQPc and the OpenMPOpt pass. There are multiple bigger tasks towards better offloading, one of which is described here https://github.com/llvm/llvm-project/issues/180 It might be interesting to add the

The first problem is that if you make a builder or .rxml file it always displays as xml in a browser. declare! it and the browser gives and error and if you change rxml to rhtml then it thinks you should be making erb. SO quetion #1 is how do I make builder files render in the browser as html. The next thing that I want to be able to do is be able to render parcials or call other files of other

Hi there!, As part of my application process to the next GSoC I'm working on the TODO in OpenMPOpt.cpp line 437:     // TODO: We should validate the declaration agains the types we expect.     Link: https://github.com/llvm/llvm-project/blob/master/llvm/lib/Transforms/IPO/OpenMPOpt.cpp#L437 I have a question.

Hola a todos: La pregunta ha quedado clara en el asunto, pero: ¿existe alguna función que convierta un objeto temporal (TS) a matriz o data.frame? En algunos cálculos que estoy haciendo me viene bien convertir un objeto temporal a matriz para poder hacer cálculos parciales por meses o años (aplicando apply en la matriz) pero no he encontrado ninguna función que haga la conversión. He «fabricado» una para el caso de frecuencia de datos mensual pero se me ha dado el caso de un objeto con frecuencia anual y ya me he empeñado en hacer la función «de carácter general...
