[R] How can I understand this sentence,and express it by means of Mathematical approach？
This topic refer to independent variables reduction, as we know ,a lot of method can do with it,however, for pre-processing independent varibles, a method like the sentence below can reduce many variable, How can I understand it? what is significant correlation at 5% level, what is the criterion？ P value？or what？ Independent variables whose correlation with the response variable was not significant at 5% level were removed how can I calucate the correlation between them? thank you! -- View this message in context: http://n4.nabble.com/How-can-I-understand-this-sentence-and-express-it-by-means-of-Mathematical-approach-tp1584036p1584036.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.
