constrMLE.difference {exact2x2} | R Documentation |
Calculate constrained MLEs.
Description
Calculate the constrained maximum likelihood estimate from 2 independent binomials for the null hypothesis parameter (difference, ratio, or odds ratio of the two binomial parameters).
Usage
constrMLE.difference(X1, N1, X2, N2, delta0)
Arguments
X1 |
vector, number of events in group 1 |
N1 |
sample size in group 1 |
X2 |
vector, number of events in group 2 |
N2 |
sample size in group 2 |
delta0 |
null parameter value |
Details
For details see Farrrington and Manning (1990) for the difference, Miettinen and Nurminen (1985) for the ratio, and Agresti and Min (2002) for the odds ratio.
Value
a list with the constrained MLE parameters, p1 and p2.
