covpCAll: Coverage Probability for 5 continuity corrected methods...

In proportion: Inference on Single Binomial Proportion and Bayesian Computations

Description

Coverage Probability for 5 continuity corrected methods (Wald, Wald-T, Score, Logit-Wald, ArcSine)

Usage

covpCAll(n, alp, c, a, b, t1, t2)

Arguments

n	- Number of trials
alp	- Alpha value (significance level required)
c	- Continiuty correction
a	- Beta parameters for hypo "p"
b	- Beta parameters for hypo "p"
t1	- Lower tolerance limit to check the spread of coverage Probability
t2	- Upper tolerance limit to check the spread of coverage Probability

Details

The Coverage Probability of 5 continuity corrected methods (Wald, Wald-T, Score, Logit-Wald, ArcSine) for n given alp, h, a, b, t1 and t2 using all the methods

Value

A dataframe with

method	Method name
MeanCP	Coverage Probability
MinCP	Minimum coverage probability
RMSE_N	Root Mean Square Error from nominal size
RMSE_M	Root Mean Square Error for Coverage Probability
RMSE_MI	Root Mean Square Error for minimum coverage probability
tol	Required tolerance for coverage probability
