%description
Provides functions to perform the Sequential Probability Ratio Test (SPRT)
for hypothesis testing in Binomial, Poisson and Normal distributions. The
package allows users to specify Type I and Type II error probabilities,
decision thresholds, and compare null and alternative hypotheses
sequentially as data accumulate. It includes visualization tools for
plotting the likelihood ratio path and decision boundaries, making it
easier to interpret results. The methods are based on Wald (1945)
<doi:10.1214/aoms/1177731118>, who introduced the SPRT as one of the
earliest and most powerful sequential analysis techniques. This package is
useful in quality control, clinical trials, and other applications
requiring early decision-making.The term 'SPRT' is an abbreviation and
used intentionally.
