Estimation equations are from a variety of sources and associated error estimation.

Methods for quality control and exploratory analysis of surface 
  water quality data collected in Massachusetts, USA.  Functions are developed 
  to facilitate data formatting for the Water Quality Exchange Network 
  <https://www.epa.gov/waterdata/water-quality-data-upload-wqx> and reporting 
  of data quality objectives to state agencies. Quality control methods are 
  from Massachusetts Department of Environmental Protection (2020) 
  <https://www.mass.gov/orgs/massachusetts-department-of-environmental-protection>.

Analyzes production and dispersal of seeds dispersed from trees and recovered in seed traps.  Motivated by long-term inventory plots where seed collections are used to infer seed production by each individual plant.

Simulates Multidimensional Adaptive Testing using the multidimensional three-parameter logistic model as described in Segall (1996) <doi:10.1007/BF02294343>, van der Linden (1999) <doi:10.3102/10769986024004398>, Reckase (2009) <doi:10.1007/978-0-387-89976-3>, and Mulder & van der Linden (2009) <doi:10.1007/s11336-008-9097-5>.

Calculates Model-Averaged Tail Area Wald
    (MATA-Wald) confidence intervals, and MATA-Wald confidence densities
    and distributions, which are constructed using single-model
    frequentist estimators and model weights. See Turek and Fletcher
    (2012) <doi:10.1016/j.csda.2012.03.002> and Fletcher et al (2019)
    <doi:10.1007/s10651-019-00432-5> for details.

Conveniently log everything you type into the R console. Logs are
    are stored as tidy data frames which can then be analyzed using 'tidyverse'
    style tools.

Calculate multiple statistics with confidence intervals for matched
    case-control data including risk difference, risk ratio, relative
    difference, and the odds ratio. Results are equivalent to those from
    'Stata', and you can choose how to format your input data. Methods used are
    those described on page 56 the 'Stata' documentation for "Epitab - Tables
    for Epidemologists" <https://www.stata.com/manuals/repitab.pdf>.
