Cluster sampling is a valuable approach when constructing a comprehensive list of individual units is challenging. It provides operational and cost advantages. This package is designed to test the efficiency of cluster sampling in terms cluster variance and design effect in context to crop surveys. This package has been developed using the algorithm of Iqbal et al. (2018) <doi:10.19080/BBOAJ.2018.05.555673>.

Index of Multiple Deprivation for UK nations at various 
    geographical levels. In England, deprivation data is for Lower Layer Super
    Output Areas, Middle Layer Super Output Areas, Wards, and Local Authorities
    based on data from <https://www.gov.uk/government/statistics/english-indices-of-deprivation-2019>.
    In Wales, deprivation data is for Lower Layer Super Output Areas, Middle 
    Layer Super Output Areas, Wards, and Local Authorities based on data from
    <https://gov.wales/welsh-index-multiple-deprivation-full-index-update-ranks-2019>.
    In Scotland, deprivation data is for Data Zones, Intermediate Zones, and 
    Council Areas based on data from <https://simd.scot>. In Northern Ireland,
    deprivation data is for Super Output Areas and Local Government Districts
    based on data from <https://www.nisra.gov.uk/statistics/deprivation/northern-ireland-multiple-deprivation-measure-2017-nimdm2017>.
    The 'IMD' package also provides the composite UK index developed by
    <https://github.com/mysociety/composite_uk_imd>.

Provides API access to the <http://imdbapi.net> which maintains metadata
             about movies, games and television shows through a public API.

Theories are one of the most important tools of science. Although psychologists discussed problems of theory in their discipline for a long time, weak theories are still widespread in most subfields. 
    One possible reason for this is that psychologists lack the tools to systematically assess the quality of their theories. 
    Previously a computational model for formal theory evaluation based on the concept of explanatory coherence was developed (Thagard, 1989, <doi:10.1017/S0140525X00057046>). 
    However, there are possible improvements to this model and it is not available in software that psychologists typically use. 
    Therefore, a new implementation of explanatory coherence based on the Ising model is available in this R-package.
