Sorry it was my mistake. I tried to do like this rm.outliers = function(model,xsys) { rst = rstudent(model) outliers<<-vector("numeric",731) xsys<<-xsys for(i in 1:length(rst)) { if(rst[i]<=3 & rst[i]>=-3) #condition for...
Hi I am trying to make some changes in data frame and return it to function .this is my function rm.outliers = function(model,xsys) { rst = rstudent(model) outliers<<-vector("numeric",10) xsys<<-xsys for(i in 1:length(rst...
Hi all, I am stuck on outlier, while doing regression analysis. I done up to modelling ,I got lm model for each y and x. Now I want to find out outlier in that models. How do I find out...
Hi , I am working on a function . rm.outliers = function(dataset,model){ dataset$predicted = predict(model) dataset$stdres = rstudent(model) m = 1 for(i in 1:length(dataset$stdres)){ dataset$outlier_counter[i] = if(dataset$stdres[i] >= 3 | dataset$stdres...
I am beginner in R doing modelling in R, I loaded excel sheet in R, i have chosen x elements and y elements then fitted model for linear and second order regression. Now I have both models. I am bit...
Hi , I am little confused about how to covert entire dataset to numeric . As I read data like.. Xelements =read.csv(file. Choose(),header = T, stringsAsFactors=FALSE) str(xelements ) > str(xelements) 'data.frame': 731 obs. of 4 variables: $ Engine.Speed...
