I am hoping to get some feedback regarding an
applied statistics and analytics website I
created to bring together acedemics and industry
analysts. It is designed to showcase academic
research and create discussion in the field of
applied statistics and to provide links to
other useful statistics
One might also ask what is meant by the 'population escape rate' in this
context. Is the data not population data?

Hi Don et al.,
If we observe one escape out of 1250 inmates, why can't we reliably rule out
zero as the population escape rate? The normal approximation to the
binomial may not be appropriate here.

I am attempting to help a friend analyze interrupted time series data,

It does seem ambitious for any survey course.
And why not teach something useful...do you prohibit them from having a
calculator? What's the difference in a calculator and a computer? I remember
learning how to take square roots, approximately...do you require them to do
that? An awful waste of

Hello, I "inherited" the reporting system for our escapes and have some
questions about how data has been reported in the past.
First, I have a question about the formula used to calculate escape rates
which is (escapes)/(average daily population - escapes). Then this is
reported as a rate per 1
