Dear Sirs, I am trying to perform a garch analysis to some data time series.Therefore, I've downloaded the package "tseries", as the garch analysis is not available in the main R program.When I try to load the "tseries package" from the R-Console screen, the following message appears: local({pkg <- select.list(sort(.packages(all.available = TRUE))) + if(nchar(pkg))

Buenas noches. Quisiera saber si existe una libreria o función que me calcule el área bajo la curva de dos vectores de números. Ademas esta debe tener en cuenta si existen datos faltantes o NaN. Por ejemplo calcular el área bajo la curva del vector en el eje x: x<- c(1,2,3,4,5,6,7,8,9,10) y el vector en el eje y: y<-c(0,2,15,30,50,NaN,NaN,10,2,1) Muchas gracias. -- *Wilmer

Estimado Wilmer Contreras Sepulveda Me parece buena la sugerencia de Jorge, hay muchas formas, yo aparte de la sugerencia que le hicieron le agrego otras dos, en cualquier buscador las palabras claves son R AUC, y el artículo https://www.r-bloggers.com/calculating-auc-the-area-under-a-roc-curve/ , lógicamente aparecerán tantas alternativas que puede llegar a confundirse respecto a cuál es

Hi we're running 3.0.1 on Solaris 9 ( with NIS/flat files as the NS ) as a member server of the AD domain ( via kinit and then net join ). there's a couple of things we've noticed and I'm not sure if they're just the way it works or configuration problems: (1) we assign the gid an uid mappings with idmap in smb.conf and I thought that winbindd would not assign uid/gids if

Hi, I am currently studying Decision Trees by using rpart package in R. I artificially created a data set which includes the dependant variable (y) and a few independent variables (x1, x2...). The dependant variable y only comprises 0 and 1. 90% of y are 1 and 10% of y are 0. When I apply rpart to it, there is no splitting at all. I am wondering whether this is because of the

Hi all, When running a prediction using RF on another data, I get two columns returned: row number(?) and predicted class. Is there a way of appending the unique row value from an ID column in the dataframe to the predictions instead of the row number? I'm assuming that the returned results follow the data frame in that the first result returned equals the first entry in the dataframe. i.e.,
