Sensitivity analysis plots for IV sensemakr

This function provides the contour plots of the sensitivity analysis results obtained with the function sensemakr for IV. It is basically a dispatcher to the core plot function ovb_contour_plot.

Usage

# S3 method for class 'iv.sensemakr'
plot(x, sensitivity.of = c("ci", "lwr", "upr", "t-value"), parm = "iv", ...)

Arguments

x

an object of class iv.sensemakr created with the sensemakr function.

sensitivity.of

should the contour plot show adjusted lower limits of confidence intervals ("lwr"), upper limit of confidence intervals ("upr") or t-values ("t-value")?

parm

contour plots of which estimate? Options are iv for instrumental variable estimates, fs for first-stage estimates, and rf for reduced-form estimates.

...

further arguments and graphical parameters.

Value

The function is called for its side effect of producing contour plots. It invisibly returns the output from ovb_contour_plot.

Examples

data("card")
y <- card$lwage
d <- card$educ
z <- card$nearc4
x <- model.matrix( ~ exper + expersq + black + south + smsa + reg661 + reg662 +
                     reg663 + reg664 + reg665+ reg666 + reg667 + reg668 + smsa66,
                   data = card)
card.fit <- iv_fit(y, d, z, x)
card.sens <- sensemakr(card.fit, benchmark_covariates = "black")
plot(card.sens, lim = 0.09)
