I am trying to do a temporal analysis of the same variable "x" over a period of 2 years. I did a qqplot(x) and discovered an almost normal relationship between the variable x over 2001 and 2002. However, there...

Hello, I need nemenyi-test or any other post-hoc test for kruskal-wallis, but I just can't find out how to implement this in R. My data set is nitrite concentrations in four different groups which I intend...

For a financial data set with large variance, I'm trying to find the outlier threshold of one variable "x" over a two year period. I qqplot(x2001, x2002) and found a normal distribution. The latter part of the normal...

Hi All, Are there times when random forests should not be used as a classification or regression model for determining variable importance. If so, then is it the properties of the training data that causes the issue? Are there other...

I am curious if there is code developed to plot confidence regions in 3D. The scatterplot3d function generates the plot I want, but would like an 3D equivalent to the data.ellipse function. Any help in this direction would be...

In R, I'm imported a data frame of 2,321,123 by 4 called "dataF". I converted the data frame "dataF" to a matrix dataM <- as.matrix(dataF) Does R have an efficient routine to treat the special elements...
