I would very much appreciate any help with the following query: I am running a regression analysis in Python using statsmodels and wish to obtain the combined effect of a number of the explanatory variables in the model. I could simply sum the individual coefficients to obtain my effect estimate but this wouldn't work for the standard errors due to covariance. Is there a straightforward way in statsmodels to derive the linear combination of coefficients?
This list is for people learning the basic python language and standard library. This question looks a tad advanced for that audience. In fact I suspect that many(most?) of the folks on this list (including me) have only a hazy idea what you are talking about in your post. However there are some data analysts amongst us so they may be able to help. If we knew what toolkits you were using to do the analysis we might be able to suggest a better forum? eg numpy, RPy or pandas? Also what version of Python you had( 2 or 3?). -- Alan G Author of the Learn to Program web site http://www.alan-g.me.uk/ http://www.flickr.com/photos/alangauldphotos _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
