I have a set of evaluation variables (n) for each sample (sample size is large enough) and I am trying to use R (nnet package) to aggregate the data. However, I don't know the weight for each variable (I am sure the weight shouldn't be equally assigned). Specifically, I have 12 indices (CO2, SO2, TSP...) for 100 cities and I want to calculate weight for each and finally obtain a comprehensive index and rankings for the cities.
Could anyone give me an idea how can I realize this? Thank you very much. -- View this message in context: http://r.789695.n4.nabble.com/Use-R-for-data-aggregation-tp4671384.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
