delfplot function

Plot graph of function delta=f(Rmax)

delfplot(parameters)

Arguments

• parameters: A vector of parameters that is generated after estimating the short, intermediate and auxiliary regressions.

Returns

A plot object created with ggplot

Examples

## Load data set
data("NLSY_IQ")
 
## Set age and race as factor variables
NLSY_IQ$age <- factor(NLSY_IQ$age)
NLSY_IQ$race <- factor(NLSY_IQ$race)
   
## Collect parameters from the short, intermediate and auxiliary regressions
parameters <- collect_par(
data = NLSY_IQ, outcome = "iq_std", 
treatment = "BF_months", 
control = c("age","sex","income","motherAge","motherEDU","mom_married","race"),
other_regressors = c("sex","age"))

## Set limits for the bounded box
Rlow <- parameters$Rtilde
Rhigh <- 0.61
deltalow <- 0.01
deltahigh <- 0.99
e <- 0.01

## Oster's method: Plot of delta = f(Rmax)
p4 <- delfplot(parameters = parameters)
print(p4)
