In inteli: Interval Estimation by Likelihood Method

Likelihood Interval for Relative Risk of 2-by-2 Contingency Table.

Description

Likelihood interval for relative risk of 2-by-2 contingency table. Likelihood function plot is also shown. For faster calculation speed, plot option '0' is recommended.

Arguments

exposure.O_event.O	a numeric vector of exposure (+) and event (+), 'a' of 2-by-2 table; mandatory
exposure.O_TOTAL	a numeric vector of exposure (+), 'a' + 'b' of 2-by-2 table; mandatory
exposure.X_event.O	a numeric vector of exposure (-) and event (-), 'c' of 2-by-2 table; mandatory
exposure.X_TOTAL	a numeric vector of exposure (-), 'c' + 'd' of 2-by-2 table; mandatory
conf.level	confidence level for the interval estimation
eps	machine epsilon value; default is 1e-08
k	cutoff value for likelihood interval. If not specified, F-test is used.

Value

demo	basic demographics of data
contin_2x2	2-by-2 contingency table
LI	estimated interval of relative risk by LI
CI	estimated interval of relative risk by CI
plot	likelihood-related plots
