Hi listers, Does anybody could tell me if there is a function for the DISTRIBUTION FUNCTION U(p;m,n)! Thanks, Marcio -- View this message in context: http://www.nabble.com/Distribution-U-tp22567871p22567871.html Sent from the R help...
Hi listers, Does anybody knows if the function qda for quadratic discriminant analysis provides the coefficients of quadratic discriminants... Well, I find out that for the linear discriminant analysis lda, the fonction provides the coefficients... Thanks in advance, Marcio -- View...
Hi listers, I check it out at the messages... But I didn't find how do I use the while with 2 conditions... while (a>1 ????? b>1){ a<-2 b<-2 } Should I use what... Thanks in advance, Marcio...
Hi Listers, Is there a way that I can transpose an array... Suppose I have the following array... x<-array(c(1,2,3,4),dim=c(1,2,2)) , , 1 [,1] [,2] [1,] 1 2 , , 2 [,1] [,2] [1...
Hi listers, I have a data frame with 5 variables... And I want reorder the data frame according a specific variable X... I checked the sort and order functions... In my case I think that the ORDER function is applicable...
Hi listers, I have a simple doubt... I need to manipulate the data base as: var1 var2 7 0.1 7 0.1 8 0.12 10 0.15 12 0.18 20 0.31 I would like to aggregate...
Hi listers, I have a statistical question corcerning the posteriori probability of a discriminant analysis. I am calculating the probabilities under R using the formula. posteriori_j=exp(q_j(y))/sum(q_j(y)) qj(y) is my quadratic...
Hi listers, I have the following code... data<-as.matrix(c(1,2,3,4,5,6,7,8,9,10),nrow=10,ncol=1,byrow=TRUE) n<-nrow(data) m<-n-1 boot<-data[sample(m,replace=T),] So...
Hi listers, I am having some trouble in a matrix multiplication... I have already checked some posts, but I didn't find my problem... I have the following code... But I am not getting the right multiplication... I checked the...
Hi listers, I am working on an canonical discriminant analysis, but I am having some trouble to use the CANDISC function... I just installed the last R version and installed the package CANDISC... But, I am getting the following message...
Hi listers, I would like to merge two vectors as follows... A<-c(3,5,7,18,43,85,91,98,100,130,230,487) #data values B<-c(10,5,5,10,8,11,2,7,3,11,10...
Hi listers, I would like a suggestion. I am working on a bootstrap simulation which I am calculation the confidence intervals to obtain the coverage probability. I am applying 3 kind of confidence intervals and 3 coverage probabilities (2 sided...
Hi listers, Suppose I have a dataset with n=10 observations and I want to sample with replacement. My new sample is of size m=9. So, I am using the following code... newsample<-dataset[sample(m,replace=T),] The...
Hi listers, First I programmed the calcul of a empirical distribution function given by: F_hat(y)=(1/n)*Sum[Ind(yi<=y)] I checked the ecdf function and I found out how does it works... A modification of the...
Hi listers, I have a problem in identifying a value between two vectors... Suppose vector A is... 0.0000 0.0909 0.0909 0.1818 0.2727 0.3636 0.4545 0.6363 0.0000 0.0000 0.0000 0...
Hi Listers, I am producing some graphics that the commands are in a FUNCTION... The problem is that I end up viewing just last graphic and in my FUNCTION there are 4 graphics with the PAR command function... Like those...
Hi all, I am using the function COV.WT to estimate the estimators (location and scale) of a bivariate cauchy distribution. My doubt is about the option WT (weight), cause at the R-help shows that the weight is uniform...
Hi listers, I've been looking for a procedure, but I am not succeding... I have a function that give multiple results... Then, I would like to simulate this function n times, so I need to save/keep the n...
