Computes delta* according to Oster (2019)
Description
Computes delta* according to Oster (2019)
Usage
osterdelstar(parameters, Rmax)
Arguments
parameters |
A vector of parameters that is generated after estimating the short, intermediate and auxiliary regressions. |
Rmax |
A real number that lies between Rtilde (R-squared for the intermediate regression) and 1. |
Value
A data frame with three columns:
delstar |
The value of delta for the chosen value of Rmax |
discontinuity |
Indicates whether the point of discontinuity is within the interval formed by Rtilde and 1 |
slope |
Slope of the function, delta=f(Rmax) |
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"))
## Oster's method: delta* (for Rmax=0.61)
osterdelstar(parameters = parameters, Rmax=0.61)
