Hi All,When carrying out hist(samples,breaks=50,probability=TRUE), the column values are considerably greater than 1, which seams very unreasonable. The plot is attached. I think the column value of the hist plot should correspond to x$counts/sum(x$counts) (x=hist(samples,breaks=50,probability=TRUE)). The size of data is a little bit larger, causing failure of uploading. If you need the data, I can email it to you. Can anyone help me?
I think you need to reread the documentation. It is a "probability density" plot, not a "probability plot." You need to integrate the values to get probabilities. Probability density functions can be bigger than 1 as long as they integrate to 1.
