plot.dfCorTest: Plot method for a dfCorTest object
Description
plot.dfCorTest, a method to plot the output of
dfCorTest. It is designed to give a quick overview
of a dfCorTest object and to check the assumption of independece between development factors.
Usage
# S3 method for dfCorTest
plot(x, type = "l", xlab = "T", ylab = "Density",
main = "Development Factor Correlation", col.area = "gray",
border = NA, …)
Arguments
x
output from dfCorTest
type
Default: "l". What type of plot should be drawn
xlab
Default: "Z". X axis label
ylab
Default: "Density". Y axis label
main
Default: "Development Factor Correlation". Plot title
col.area
Default: "gray". Color of the shaded area.
border
Default: NULL, the color to draw the border. Use border = NA to omit borders.
…
optional arguments. See plot.default for
more details.
Details
plot.dfCorTest shows the underlying distribution, the test statistic \(Z\) and the relative Confidence Interval.
If the test statistic \(Z\) is within the highlighted region the hypothesis of correlation between development factors could be rejected.
