nonprobsvy 0.1.1
Bugfixes
bug Fix occuring when estimation was based on auxiliary variable, which led to compression of the data from the frame to the vector.
bug Fix related to not passing maxit argument from controlSel function to internally used nleqslv function
bug Fix related to storing vector in model_frame when predicting y_hat in mass imputation glm model when X is based in one auxiliary variable only - fix provided converting it to data.frame object.
Features
add information to summary about quality of estimation basing on difference between estimated and known total values of auxiliary variables
add estimation of exact standard error for k-nearest neighbor estimator.
add breaking change to controlOut function by switching values for predictive_match argument. From now on, the predictive_match = 1 means $\hat{y}-\hat{y}$ in predictive mean matching imputation and predictive_match = 2 corresponds to $\hat{y}-y$ matching.
implement div option when variable selection (more in documentation) for doubly robust estimation.
add more insights to nonprob output such as gradient, hessian and jacobian derived from IPW estimation for mle and gee methods when IPW or DR model executed.
add estimated inclusion probabilities and its derivatives for probability and non-probability samples to nonprob output when IPW or DR model executed.
add model_frame matrix data from probability sample used for mass imputation to nonprob when MI or DR model executed.
Unit tests
added unit tests for variable selection models and mi estimation with vector of population totals available
