plotMisfit: Plot the population misfit in the result object

Description

Plot a histogram of the amount of population misfit in parameter result object or the scatter plot of the relationship between misspecified parameter and the population misfit or the fit indices

Usage

plotMisfit(object, usedFit="default", misParam=NULL)

Arguments

object

The result object, SimResult

usedFit

The sample fit indices or population misfit used to plot. All sample fit indices are available. The available population misfit are "pop.f0", "pop.rmsea", and "pop.srmr". If the misParam is not specified

misParam

The index or the name of misspecified parameters used to plot.

Value

• None. This function will plot only.

Examples

path.BE <- matrix(0, 4, 4)
path.BE[3, 1:2] <- NA
path.BE[4, 3] <- NA
starting.BE <- matrix("", 4, 4)
starting.BE[3, 1:2] <- "runif(1, 0.3, 0.5)"
starting.BE[4, 3] <- "runif(1, 0.5, 0.7)"
mis.path.BE <- matrix(0, 4, 4)
mis.path.BE[4, 1:2] <- "runif(1, -0.1, 0.1)"
BE <- bind(path.BE, starting.BE, misspec=mis.path.BE)

residual.error <- diag(4)
residual.error[1,2] <- residual.error[2,1] <- NA
RPS <- binds(residual.error, "rnorm(1, 0.3, 0.1)")

ME <- bind(rep(NA, 4), 0)

Path.Model <- model(RPS = RPS, BE = BE, ME = ME, modelType="Path")

# The number of replications in actual analysis should be much more than 20
Output <- sim(20, n=500, Path.Model)

# Plot the distribution of population misfit
plotMisfit(Output)

# Plot the relationship between population RMSEA and all misspecified direct effects
plotMisfit(Output, misParam=1:2)

# Plot the relationship between sample CFI and all misspecified direct effects 
plotMisfit(Output, usedFit="CFI", misParam=1:2)
