About stepwise regression problem
First of all, I have GAMs noxd<-gam(newNOX~pressure+maxtemp+s(avetemp,bs="cr")+s(mintemp,bs="cr")+s(RH,bs="cr")+s(solar,bs="cr")+s(windspeed,bs="cr")+s(transport,bs="cr"),family=gaussian (link=log),groupD,methods=REML) Then I type " summary(noxd)". and show Family: gaussian Link function: log Formula: newNO2 ~ pressure

Very confused with class
Hi all, I am very confused with class. I am looking at some weather data which I want to use as explanatory variables in an lm.

Question about GAMs
hi! I hope all of you can help me this question for example GAMs: ozonea<-gam(newozone~ pressure+maxtemp+s(avetemp,bs="cr")+s(ratio,bs="cr"),family=gaussian (link=log),groupA,methods=REML) formula(ozonea) newozone ~ pressure + maxtemp + s(avetemp, bs = "cr") + s(ratio,bs = "cr") #formula of gams coef(ozonea) # extract the coefficient of GAMs

Hi all, I have a 2 files, one with a series of beginning and end times of animal dives in (lets call it dives). The other file is readings from a time-depth recorder, there is a datetime reading for every second, a temperature and light level reading (lets call it tdr). Now I want to say from the file dives, using the start and end time of the dives, go to the tdr file and find me the

Data Parameter extract
Hi, So I have a set of data, hourly temperature, where each temperature is set up like this: Time Temp 1.04 8 1.08 10 etc. Where "1" corresponds to a day (say monday is "1", tuesday is "2") and the decimal value corresponds to an the hour of the day. I have several thousand of these readings over several months. What I would like to do is
