Hi!
I have a data set of 86 values that are non-normally distributed (counts).
The median value is 10. I want to get an estimate of the 95% confidence
interval for this median value.
I tried to use a one-sample Wiolcoxin test:
wilcox.test(Comps,mu=10,conf.int=TRUE)
and got the following output:
Wilcoxon signed rank test with continuity correction
data: Comps
V = 2111, p-value = 0.05846
alternative hypothesis: true location is not equal to 10
95 percent confidence interval:
10.00000 17.49993
sample estimates:
(pseudo)median
12.50006
I wonder if someone would mind helping me out?
What am I doing wrong?
What is the '(psuedo)median'?
Can I get R to estimate the confidence around the actual median of 10?
With thanks,
Georgie
