Mpre {forestPSD} | R Documentation |
Time sequence prediction for the population dynamic changes.
Description
The renewal ability of populations was simulated and predicted using the moving average method.
Usage
Mpre(ax,n=c(2,4,6))
Arguments
ax |
Population number of within different age class. |
n |
Number of periods to average over. Must be between 1 and nrow(x), inclusive. |
Details
The renewal ability of populations was simulated and predicted using the moving average method.
Value
Result returns the results of the simulated and predicted the population dynamic changes using the moving average method.
