Subject: [R] Stepwise regression and partial correlation for wildlife census
time series
Dear List;
We are doing a time series analysis of wildlife census data. We use a
stepwise regression of the annual per capita rate of increase against
pervious years population size (log transformed) as suggested by
Berryman & Turchin (2001, Oikos 92:265-270).
How can we obtain the partial correlation coefficients in R to make a
plot of them against the lag as in a standard PACF?
Yours Sincerely
Tomas Willebrand
