dynEGA.ind.pop {EGAnet}  R Documentation 
Dynamic EGA used in the mctest.ergoInfo function. DynEGA estimates dynamic factors in multivariate time series (i.e. longitudinal data, panel data, intensive longitudinal data) at multiple
time scales, in different levels of analysis: individuals (intraindividual structure) and population (structure of the population).
Exploratory graph analysis is applied in the derivatives estimated using generalized local linear approximation (glla
). Instead of estimating factors by modeling how variables are covarying, as in traditional
EGA, dynEGA is a dynamic model that estimates the factor structure by modeling how variables are changing together.
GLLA is a filtering method for estimating derivatives from data that uses time delay embedding and a variant of SavitzkyGolay filtering to accomplish the task.

data 
A dataframe with the variables to be used in the analysis. The dataframe should be in a long format (i.e. observations for the same individual (for example, individual 1) are placed in order, from time 1 to time t, followed by the observations from individual 2, also ordered from time 1 to time t.) 
n.embed 
Integer.
Number of embedded dimensions (the number of observations to be used in the 
tau 
Integer.
Number of observations to offset successive embeddings in the 
delta 
Integer.
The time between successive observations in the time series.
Default is 
id 
Numeric. Number of the column identifying each individual. 
use.derivatives 
Integer. The order of the derivative to be used in the EGA procedure. Default to 1. 
model 
Character.
A string indicating the method to use. Defaults to

model.args 
List.
A list of additional arguments for 
algorithm 
A string indicating the algorithm to use or a function from Current options are:

algorithm.args 
List.
A list of additional arguments for 
corr 
Type of correlation matrix to compute. The default uses

ncores 
Numeric.
Number of cores to use in computing results.
Defaults to If you're unsure how many cores your computer has,
then use the following code:
