EDMfun0: EDM deterministic function

In pttstability: Particle-Takens Stability

EDM deterministic function

Description

Estimates future states of xt based on based behaviour

Usage

EDMfun0(smp_cf, yp, x, minest = 0, maxest = NULL, time)

Arguments

smp_cf	a matrix of s-map coefficients. Columns correspond to intercept and time lags, rows to observations. Final column corresponds to intercept term.
yp	a matrix of covariates to be multiplied by the smp_cf (typically time lags). Should have one fewer column than smp_cf.
x	observation at time-1, to be used to make the prediction.
minest	minimum value to return for prediction - defaults to 0.
maxest	maximum value to return for prediction - defaults to NULL (no maximum)
time	the time step (i.e. position in smp_cf) for the desired prediction. Prediction will be made based on observation in preceding time point (i.e. time-1).

Value

a number or numeric vector of length xt, with predicted abundances at time t+1
