dlsem (version 1.4)

lagPlot: Plot lag shapes

Description

Plot the lag shape associated to a path or an overall causal effect.

Usage

lagPlot(model, from = NULL, to = NULL, path = NULL, maxlag = NULL, cumul = FALSE, conf = 0.95, ylim = NULL, title = NULL)

Arguments

model

An object of class dlsem.

from

The name of the covariate.

to

The name of the response variable.

path

The name of the path, indicated as a string made of the names of the variables in the path separated by '*'. Ignored if both from and to are not NULL.

maxlag

The maximum lag displayed (optional).

cumul

Logical. If FALSE (the default), instantaneous path coefficients are returned, otherwise cumulative ones are provided.

conf

The confidence level for edges in the object of class dlsem. Default is 0.95.

ylim

A vector of two numerical values indicating the limits of the y axis (optional). If NULL, the limits of the y axis are computed automatically.

title

The title of the plot (optional). If NULL, a default title is used.

Examples

data(agres)
mycode <- list(
  GVA~quec(NPATENT,1,15),
  PPI~quec(NPATENT,0,13)+quec(GVA,0,14),
  ENTR_INCOME~quec(NPATENT,0,14)+quec(GVA,1,14)
  )
myfit <- dlsem(mycode,group="COUNTRY",exogenous=c("GDP","FARM_SIZE"),
  data=agres,uniroot.check=TRUE,imputation=FALSE,log=TRUE)

# the lag shape associated to specific paths
lagPlot(myfit,path="NPATENT*PPI")
lagPlot(myfit,path="NPATENT*GVA*PPI")

# the lag shape associated to an overall causal effect
lagPlot(myfit,from="NPATENT",to="PPI")
