At the European Geosciences Union Meeting (Spring 2017 in Vienna) there will be an interactive sessionthat aims to bring together scientists that share a common indispensable tool: the statistic software R. http://meetingorganizer.copernicus.org/EGU2017/session/24971 We have the feeling that R

[R] (Seismic) signal deconvolution with R

Has anybody (successfully) tried to deconvolve a seismic signal (time series in general) using R and package signal? I have the Matlab routines: [bb,aa] = zp2tf(zero,pole',gain); [bb,aa] = bilinear(bb,aa,df); transfer = freqz(bb,aa,f,df); But the (apparent) equivalents of R produce quite

[R] fit data with y = x^-1

Dear list, I am getting weired with fitting data with a 1/x-polynomial. Suggest I have the following data: x - c(1,2,3,4,5,6,7) y - c(100,20,4,2,1,.3,.1) I may fit this with a linear model fit1 = lm(y ~ I(x)) Getting plot out of this model I applied library(polynom) pol1 =
