plot.ci {Zelig} | R Documentation |
The plot.ci
command generates vertical
confidence intervals for linear or generalized linear univariate
response models.
plot.ci(x, CI = 95, qi = "ev", main = "", ylab = NULL, xlab = NULL, xlim = NULL, ylim = NULL, col = c("red", "blue"), ...)
x |
stored output from sim . The x$x and optional
x$x1 values used to generate the sim output object must
have more than one observation. |
CI |
the selected confidence interval. Defaults to 95 percent. |
qi |
the selected quantity of interest. Defaults to expected values. |
main |
a title for the plot. |
ylab |
label for the y-axis. |
xlab |
label for the x-axis. |
xlim |
limits on the x-axis. |
ylim |
limits on the y-axis. |
col |
a vector of at most two colors for plotting the
expected value given by x and the alternative set of expected
values given by x1 in sim . If the quantity of
interest selected is not the expected value, or x1 = NULL ,
only the first color will be used. |

For all univariate response models, {tt plot.ci()} returns vertical confidence intervals over a specified range of one explanatory variable. You may save this plot using the commands described in the Zelig manual (http://gking.harvard.edu/zelig).
