Fisher null hypothesis
WebFisher thought that the p-value could be interpreted as a continuous measure of evidence against the null hypothesis. There is no particular fixed value at which the results … WebDescription An implementation of randomization-based hypothesis testing for three different estimands in a cluster-randomized encouragement experiment. The three estimands include (1) testing a cluster-level constant proportional treatment effect (Fisher's sharp null hypothesis), (2) pooled effect ratio, and (3) average cluster effect ratio.
