R. Mutz et Uh. Sauter, DATA-ANALYSIS STRATEGIES IN FOREST RESEAR CH - DATABOX AND MULTIVARIATE CROSSPRODUCT-PARTITIONING (MCP) WITH WOOD SCIENCE SERVING AS AN EXAMPLE, Forstwissenschaftliches Centralblatt, 115(3), 1996, pp. 193-201
The inhomogeneity of wood as a raw and working material must be accept
ed as one of the basic empirical facts of wood science (GRAMMEL 1989;
HOLZ 1965). Different influencing factors are responsible for this, e.
g. growth conditions or the position of a sample in the tree. With the
Multivariate Crossproduct-Partitioning (MCP) or Databox Partitioning
described in this paper a statistical concept for differential wood sc
ience is proposed, whose central issue is the description, explanation
, prediction and control of wood properties in relation to growth cond
itions. An example from a wood science project by SAUTER (1992) serves
to illustrate this strategy. The transfer of this formal concept to o
ther branches of forest science appears both sensible and feasible.
