Table VIII-3. | The age stages ranked according to k*sd values as found with a key-factor analysis of data from a simulation of field data (see text) |
rp = | productmoment correlation coefficients between k-values and the K-factor per period |
ry = | productmoment correlation coefficients between k-values and the K-factor of the total year |
