Left, right or interval censored mixed-effects linear model with autoregressive errors of order p or DEC correlation structure using the type-EM algorithm. The error distribution  can be Normal or t-Student. It provides the  parameter estimates, the standard errors  and prediction of future observations (available only for the normal case).

Tools for simulating data generated by direct observation
    recording. Behavior streams are simulated based on an alternating renewal
    process, given specified distributions of event durations and interim
    times. Different procedures for recording data can then be applied to the
    simulated behavior streams. Functions are provided for the following
    recording methods: continuous duration recording, event counting, momentary
    time sampling, partial interval recording, whole interval recording, and
    augmented interval recording.

Provides convenience functions for programming with
    'magrittr' pipes. Conditional pipes, a string prefixer and a function
    to pipe the given object into a specific argument given by character
    name are currently supported. It is named after the dadaist Hans Arp,
    a friend of Rene Magritte.

Functions for Arps decline-curve analysis on oil and gas data. Includes exponential, hyperbolic, harmonic, and hyperbolic-to-exponential models as well as the preceding with initial curtailment or a period of linear rate buildup. Functions included for computing rate, cumulative production, instantaneous decline, EUR, time to economic limit, and performing least-squares best fits.

Fast generators and iterators for permutations, combinations,
    integer partitions and compositions. The arrangements are in
    lexicographical order and generated iteratively in a memory efficient manner. 
    It has been demonstrated that 'arrangements' outperforms most existing
    packages of similar kind. Benchmarks could be found at
