Effect of thinning on individual tree growth
Description
A time series of estimated effect of thinning on the annual basal area growth of a
Scots pine tree.
Usage
data(thinning)
Format
A data frame with 23 observations on the following 3 variables.
TreeIDTree ID, 3_3 for all observations in this data.
YearCalendar year (1983-2005).
ThEffEstimated effect of thinning on the annual basal area growth in mm^2.
Details
The thinning took place between years 1986 and 1987. For details about the original measurements, see the documentation of data set patti, afterthin. For details about the procedure used
in extracting the thinning effect, see Example 6.6 in Mehtatalo and Lappi 2020b and for nonlinear modeling of this data, see Chapter 7 of Mehtatalo and Lappi 2020a.
