Generates a basic plot of estimated coefficients which are subject to constraints (theta_1 ). Lines indicate individual constraints (not global tests) and significance.
Usage
## S3 method for class 'summary.clme'
plot(x, alpha = 0.05, legendx = "below",
inset = 0.01, ci = FALSE, ylim = NULL, cex = 1.75, pch = 21,
bg = "white", xlab = expression(paste("Component of ", theta[1])),
ylab = expression(paste("Estimated Value of ", theta[1])), tree = NULL,
...)
Arguments
x
object of class 'clme' to be plotted.
alpha
significance level of the test.
legendx
character indicating placement of legend. See Details.
inset
inset distance(s) from the margins as a fraction of the plot region when legend is placed by keyword.
ci
plot individual confidence intervals.
ylim
limits of the y axis.
cex
size of plotting symbols.
pch
plotting symbols.
bg
background (fill) color of the plotting symbols.
xlab
label of the x axis.
ylab
label of the y axis.
tree
logical to produce alternate graph for tree ordering.
...
additional plotting arguments.
Details
All of the individual contrasts in the constraints$A matrix are tested and plotted.
The global test is not represented (unless it happens to coincide with an individual contrast).
Only the elements of theta which appear in any constraints (e.g. the elements of
theta_1) are plotted. Coefficients for the covariates are not plotted.
Solid lines denote no significant difference, while dashed lines denote statistical significance.
Significance is determined by the individual p-value being less than or equal to the supplied
alpha threshold. By default a legend denoting the meaning of solid and dashed lines
will be placed below the graph. Argument legendx may be set to a legend keyword (e.g.
legend=''bottomright'') to place it inside the graph at the specified location. Setting
legendx to FALSE or to a non-supported keyword suppresses the legend.
Confidence intervals for the coefficients may be plotted. They are individual confidence intervals,
and are computed using the covariance matrix of the unconstrained estimates of
theta_1. These confidence intervals have higher coverage probability than the
nominal value, and as such may appear to be in conflict with the significance tests. Alternate
forms of confidence intervals may be provided in future updates.#'
