问题 This question was migrated from Cross Validated because it can be answered on Stack Overflow. Migrated 4 years ago . I have a hierarchical time series, the bottom level series of which all exhibit intermittent demand. It seems advantageous to use Hyndman's HTS package for optimal combination within the hierarchy. It also seems advantageous to use Kourentzes' MAPA package for multiple aggregation prediction of the intermittent demand. In essence, I want to do something like: forecast(my_hts,

hierarchical cluster labeling with plots

由 喜你入骨 提交于 2019-12-06 08:37:38
I have a distance matrix for ~20 elements, which I am using to do hierarchical clustering in R. Is there a way to label elements with a plot or a picture instead of just numbers, characters, etc? So, instead of the leaf nodes having numbers, it'd have small plots or pictures. Here is why I'm interested in this functionality. I have 2-D scatterplots like these (color indicates density) http://www.pnas.org/content/108/51/20455/F2.large.jpg (Note that this is not my own data) I have to analyze hundreds of such 2-D scatter plots, and am trying out various distance metrics which I'm feeding on to

In essence, I want to do something like: forecast(my_hts, method='comb', fmethod='MAPA') However, it is unclear to me if / how I can combine the two, since forecast.gts() only accepts fmethod=c("ets", "arima", "rw"). Is there a clever way to pass different forecasting methods to
