Confidence intervals of PsN bootstrap output
Hello everyone,
I am using PsN to do some bootstrap and have some questions regarding the
PsN output.
1. There are two confidence interval (CI) reported in the output file
"bootstrap_results.csv":
standard.error.confidence.intervals
percentile.confidence.intervals
I wonder which one should be used in the publication or report, and what is
the difference between them.
2. When I use excel function
"=PERCENTILE(T5:T505,5%)" and "=PERCENTILE(T5:T505,95%)" to calculate the 5%
and 95% percentile of a parameter from the data "raw_results1.csv" the
result is different from both "standard.error.confidence.intervals" and "
percentile.confidence.intervals".
The same happens to the excel function "=MEDIAN(T5:T505)" result and
the"medians" in the "bootstrap_results.csv".
Does anyone know why it is the case, and which value I should use?
bootstrap_results.csv
medians
423.5635
standard.error.confidence.intervals
5% 419.73239
95% 428.26761
percentile.confidence.intervals
5% 419.56165
95% 427.9239
Excel calculation from raw_results1.csv
Median 423.578
5% percentile 419.593
95% percentile 427.922
Thanks,
Norman
