Likelihood Interval of variance and sd assuming Norml Distribution using sufficient statistics
Description
Likelihood interval of variance and sd assuming normal distribution. This is estimated likelihood interval, not profile likelihood interval.
Usage
LIvtest(m1, s1, n1, m2, s2, n2, k, conf.level=0.95)
Arguments
m1 |
sample mean of the first group |
s1 |
sample standard deviation of the first group |
n1 |
sample size of the first group |
m2 |
sample mean of the second group |
s2 |
sample standard deviation of the second group |
n2 |
sample size of the second group |
k |
1/k likelihood interval will be calculated |
conf.level |
approximate confidence level. If k is specified, this is ignored. |
Details
It calculates likelihood interval of variance and sd using sufficient statistics. There is no standard error in the output.
Value
PE |
point estimation for the proportion |
LL |
lower limit of likelihood interval |
UL |
upper limit of likelihood interval |
logk |
log(k) value used for LI |
maxLL |
maximum log likelihood |
conf.level |
approximate confidence level |
