Description
Computes parameter bounds to be used in L-BFGS-B mle optimization.
Usage
1
Arguments
data
data frame containing cols y (positive outcome with zeros) and z (treatment).
Details
For the input data frame, column z is the dummy variable for treatment. If z = 1, then the observation has received treatment.
If z = 0, then the observation has not received treatment.
Each strata must have at least three observations.
According to RDocumentation, the L-BFGS-B method for optimization is taken from Byrd et. al. (1995), allowing box constraints with
upper and lower bound.
Value
The maximum and lowest possible values for segment proportions, mean, and variance.
Examples

sim = sim_latent_strat(n=10000, piA=0.2, piB=0.1, muA1=5, muA0=4.5, muB1=3, sigma=0.3)
