Estimation of function and index vector in single index model ('sim')
    with (and w/o) shape constraints including different smoothness conditions.
    See, e.g., Kuchibhotla and Patra (2020) <doi:10.3150/19-BEJ1183>.

Supports the calculation of meteorological characteristics in 
      evapotranspiration research and reference crop evapotranspiration, and offers 
      three models to simulate crop evapotranspiration and soil water balance in 
      the field, including single crop coefficient and dual crop coefficient, 
      as well as the Shuttleworth-Wallace model. These calculations main refer to 
      Allen et al.(1998, ISBN:92-5-104219-5), Teh (2006, ISBN:1-58-112-998-X), and 
      Liu et al.(2006) <doi:10.1016/j.agwat.2006.01.018>.

Monte Carlo simulations of a game-theoretic model for the 
	legal exemption system of the European cartel law are implemented
	in order to estimate the (mean) deterrent effect of this system.
	The input and output parameters of the simulated cartel 
	opportunities can be visualized by three-dimensional projections.
	A description of the model is given in Moritz et al. (2018)
	<doi:10.1515/bejeap-2017-0235>.

Simulate event history data from a framework where treatment decisions 
    and disease progression are represented as counting process. The user can specify 
    number of events and parameters of intensities thereby creating a flexible 
    simulation framework.

Generates binary test data based on Item Response Theory using the two-parameter logistic model (Lord, 1980 <doi:10.4324/9780203056615>). Useful functions for test equating are included, e.g. functions for generating internal and external common items between test forms and a function to create a linkage plans between those forms. Ancillary functions for generating true item and person parameters as well as for calculating the probability of a person correctly answering an item are also included.
