Create a Pareto Plot of Effects
DESCRIPTION:
Creates a Pareto plot (vertical bar plot) of t-values obtained from a response surface fit.
USAGE
:
pareto(x, sig=.05, prt.values = T, shade = F,...)
REQUIRED ARGUMENTS
:
x
:
output from fitting a response surface using
rsm.lm
.
OPTIONAL ARGUMENTS
:
sig
:
significance level for t-distribution significance. lines.
prt.values
:
a logical flag for whether values are printed at end of bars.
shade
:
logical flag for whether will be shaded or filled with solid colors.
...
:
graphical pars passed to barplot (see
par
).
SIDE EFFECTS:
A Pareto plot of t-statistics from response surface fit is plotted on the current graphics device.
