get_sample_d

Calculate sample size and decision rule for a specified LQAS sampling plan

In the recent past, measurement of coverage has been mainly through
two-stage cluster sampled surveys either as part of a nutrition assessment
or through a specific coverage survey known as Centric Systematic Area
Sampling (CSAS). However, such methods are resource intensive and often only
used for final programme evaluation meaning results arrive too late for
programme adaptation. SLEAC, which stands for Simplified Lot Quality
Assurance Sampling Evaluation of Access and Coverage, is a low resource
method designed specifically to address this limitation and is used
regularly for monitoring, planning and importantly, timely improvement to
programme quality, both for agency and Ministry of Health (MoH) led
programmes. SLEAC is designed to complement the Semi-quantitative Evaluation
of Access and Coverage (SQUEAC) method. This package provides functions for
use in conducting a SLEAC assessment.
