  "Description": "Given the maximum available sample size (N) for an\nexperiment, and the target levels of Type I and II error\nprobabilities, this package designs a modified SPRT (MSPRT).\nFor any designed MSPRT the package can also obtain its\noperating characteristics and implement the test for a given\nsequentially observed data. The MSPRT is defined in a manner\nvery similar to Wald's initial proposal. The proposed test has\nshown evidence of reducing the average sample size required to\nperform statistical hypothesis tests at specified levels of\nsignificance and power. Currently, the package implements\none-sample proportion tests, one and two-sample z tests, and\none and two-sample t tests. A brief user guidance for this\npackage is provided below. One can also refer to the\nsupplemental information for the same.",
