sprtt: Sequential Probability Ratio Tests Toolbox

Description

A toolbox for Sequential Probability Ratio Tests (SPRT) based on Wald (1945) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.2134/agronj1947.00021962003900070011x")}. SPRTs are applied during the sampling process, ideally after each observation, and at every stage return a decision to either continue sampling or terminate and accept one of the specified hypotheses. The 'seq_ttest()' function performs one-sample, two-sample, and paired t-tests for one- and two-sided hypotheses (Schnuerch & Erdfelder (2019) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1037/met0000234")}). The 'seq_anova()' function performs a sequential one-way fixed effects ANOVA (Steinhilber et al. (2024) \Sexpr[results=rd]{tools:::Rd_expr_doi("10.1037/met0000677")}). The 'plan_sample_size()' function helps plan sequential studies by simulating required sample sizes across a range of effect sizes.
