Hi I have a regression based data where I get the RMSE results as: SVM=3500 ANN=4600 R.Forest=2900 I want to know how can I make it so that its values comes as 0-1 I plot the boxplot for it to indicate their RMSE values and used, ylim=(0,1), but the boxplot which works for RMSE values like 3500 etc, but when I use ylim=(0,1), all the boxplots suddenly disappears. What should I do for it? Thanks [[alternative HTML version deleted]]
Hello,
To rescale data so that their values are between 0 and 1, use this function:
scale01 <- function(x, na.rm = FALSE){
(x - min(x, na.rm = na.rm))/(max(x, na.rm = na.rm) - min(x, na.rm =
na.rm))
}
x <- c(SVM=3500,
ANN=4600,
R.Forest=2900)
scale01(x)
# SVM ANN R.Forest
#0.3529412 1.0000000 0.0000000
See base R function ?scale for another way of scaling data.
As for the second question, if your RMSE vector had values in the range
2900 to 4600 and the y axis limits are c(0, 1), how can you expect to
see anything?
Hope this helps,
Rui Barradas

Thanks Hasan and Rui Rui, as you mentioned As for the second question, if your RMSE vector had values in the range 2900 to 4600 and the y axis limits are c(0, 1), how can you expect to see anything? Then what should be the values of ylim in boxplots? I need to show them as boxplot between 0-1 or 1-10, even 10-100 but it will be very awkward if the boxplot shows the values of 3500 etc. Regards On Thu, Mar 12, 2020 at 11:51 PM Rui Barradas <ruipbarradas at sapo.pt> wrote:> Hello, > > To rescale data so that their values are between 0 and 1, use this > function: > > > scale01 <- function(x, na.rm = FALSE){ > (x - min(x, na.rm = na.rm))/(max(x, na.rm = na.rm) - min(x, na.rm > na.rm)) > } > > x <- c(SVM=3500, > ANN=4600, > R.Forest=2900) > > scale01(x) > # SVM ANN R.Forest > #0.3529412 1.0000000 0.0000000 > > > See base R function ?scale for another way of scaling data. > > As for the second question, if your RMSE vector had values in the range > 2900 to 4600 and the y axis limits are c(0, 1), how can you expect to > see anything? > > Hope this helps, > > Rui Barradas > > > ?s 21:08 de 12/03/20, Neha gupta escreveu: > > Hi > > > > I have a regression based data where I get the RMSE results as: > > > > SVM=3500 > > ANN=4600 > > R.Forest=2900 > > > > I want to know how can I make it so that its values comes as 0-1 > > > > I plot the boxplot for it to indicate their RMSE values and used, > > ylim=(0,1), but the boxplot which works for RMSE values like 3500 etc, > but > > when I use ylim=(0,1), all the boxplots suddenly disappears.

Hi, Why do you want to re-scale RMSE to 0-1? You can change ylim=(0,1) to ylim=(0, 4600). You may use VEcv (Variance explained by predictive models based on cross-validation) that ranges from 0 to 100% instead. It can be calculated using vecv function in library(spm) or you can convert RMSE to VEcv using tovecv in spm.

Thanks a lot Jin.. If my total number of observations are 500, n will be 500, mu will be average (500) s will be sd (500) and m will be RMSE value i.e. 4500 in this case? tovecv(n=500, mu=average (500), s=sd, m=4500, measure="rmse") On Fri, Mar 13, 2020 at 12:46 AM Jin Li <jinli68 at gmail.com> wrote:> Hi, > Why do you want to re-scale RMSE to 0-1?
