View source: R/weight_continuous.R

Description

Compute weight from the probability of the rank given the effect size for the continuous effect size

Usage

1
weight_continuous(alpha, et, m, tail = 1L, delInterval = 0.001, ranksProb)

Arguments

alpha

Numeric, significance level of the hypothesis test

et

Numeric, mean effect size of the test statistics

m

Integer, totoal number of hypothesis test

tail

Integer (1 or 2), right-tailed or two-tailed hypothesis test. default is right-tailed test.

delInterval

Numeric, interval between the delta values of a sequence. Note that, delta is a LaGrange multiplier, necessary to normalize the weight

ranksProb

Numeric vector of ranks probability of the tests given the effect size

Details

If one wants to test

H_0: epsilon_i = 0 vs. H_a: ε_i > 0,

then et and ey should be mean value of the test and covariate effect sizes, respectively. This is called hypothesis testing for the continuous effect sizes.

Value

weight Numeric vector of normalized weight of the tests for the continuous case

# compute the probabilities of the ranks of a test being rank 1 to 100 if the

                              m0 = 50, m1 = 50)

# plot the prooabbility
plot(ranks, prob2)

# compute weight for the continuous case

                                     delInterval = .0001, ranksProb = prob2)

# plot the weight
