This repository has R codes for Fast Optimal Subsampling Probability Approximation for Generalized Linear Models
Datageneration.R generate simulated data
FASA_linear.R calculate estimates based on the approximated subsampling probability under linear regression
FASA_logistic.R calculate estimates based on the approximated subsampling probability under logistic regression
Example.R provides an example how to perform estimates with the above codes and a simulated data
