Thanks for reaching out with your question on the package.
1) If you want the parameters fitted to each segment then you can access these using:
param.est(pelt)
2) By default the plot function for cpt.meanvar will add the mean lines to the original signal. You can change the width of these lines using cpt.width and colour using cpt.col options to the plot function.
plot(pelt,cpt.width=3,col='blue')
You may find the Journal of Statistical Software paper helpful in describing the features of the package. It is available as open access from here: https://www.jstatsoft.org/article/view/v058i03
If you have any further questions, please just ask.
Dear developer,
Thank you for this useful package!
I have already use cpt.meanvar to process my data. By the code:
pelt <- cpt.meanvar(mydata$height, test.stat = "Poisson", method = "BinSeg")
by the following code, I get the potential change points : [1] 2141 2518 3180
cpts(dis.pelt)
I have two questions: (1) how can I get the represented value for each following segment?:
0-2140 2142 - 2517 2519 - 3179 3181 - 5000
(2) how can I put these value of the plot? Maybe some parameter in plot(pelt) ?
Best
