In inteli: Interval Estimation by Likelihood Method

Testing Function for Mean Difference of Two Samples from Normal Distribution by LI Method

Description

Testing function for mean difference of two samples assuming normal distribution by LI method. O2 type likelihood function plot is also shown.

Arguments

set.a	a numeric vector of former data values; mandatory
set.b	a numeric vector of latter data values; mandatory
conf.level	confidence level for the interval estimation
df	degree of freedom for likelihood interval; default is 1
k	cutoff value for likelihood interval. If not specified, F-test is used.

Value

demo	basic demographics of data
interval	estimated interval by LI and CI. PE is mean(set.a) - mean(set.b).
stat	statistical values, such as p-value and likelihood ratio
verdict	estimation result as a sentence
plot	log likelihood function plot (O2 type)
