### Features | ||
|
||
- implemented population mean estimation using doubly robust, inverse probability weighting and mass imputation methods | ||
- implemented inverse probability weighting models with Maximum Likelihood Estimation and Generalized Estimating Equations methods with `logit`, `complementary log-log` and `probit` link functions. | ||
- implemented `generalized linear models`, `nearest neighbours` and `predictive mean matching` methods for Mass Imputation | ||
- implemented estimation methods when vector of population means/totals is available | ||
- implemented variables selection with `SCAD`, `LASSO` and `MCP` penalization equations | ||
- implemented `analytic` and `bootstrap` (with parallel computation) variance for described estimators | ||
- added control parameters for models | ||

- implemented bias correction estimators for doubly-robust approach | ||
- implemented estimation methods when vector of population means/totals is available | ||
- implemented variables selection with `SCAD`, `LASSO` and `MCP` penalization equations | ||
- implemented `analytic` and `bootstrap` (with parallel computation - `doSNOW` package) variance for described estimators | ||
- added control parameters for models | ||
- added S3 methods for object of `nonprob` class such as | ||
- `nobs` for samples size | ||
- `pop.size` for population size estimation | ||
- `residuals` for residuals of the inverse probability weighting model | ||
- `cooks.distance` for identifying influential observations that have a significant impact on the parameter estimates | ||
- `hatvalues` for measuring the leverage of individual observations | ||
- `logLik` for computing the log-likelihood of the model, | ||
- `AIC` (Akaike Information Criterion) for evaluating the model based on the trade-off between goodness of fit and complexity, helping in model selection | ||
- `BIC` (Bayesian Information Criterion) for a similar purpose as AIC but with a stronger penalty for model complexity | ||
- `confint` for calculating confidence intervals around parameter estimates | ||
- `vcov` for obtaining the variance-covariance matrix of the parameter estimates | ||
- `deviance` for assessing the goodness of fit of the model | ||
