Referring your example:
variance = 2_nd moment - (1_st moment),
that is:
2_nd moment = 0^2 * 0.2 + 1^2 * 0.3 + 2^2 * 0.2 + 3^2 * 0.2 + 4^2 * 0.1 =
4.5
1_st moment = 0 * 0.2 + 1 * 0.3 + 2 * 0.2 + 3 * 0.2 + 4 * 0.1 = 1.7
then
variance = 4.5 - (1.7)^2 = 1.61
then
standard deviation = sqrt(1.61) =

Of course, it's of strong advantage to use computers as reference
tools, however, exactly the same tools are frequently used 'against'
patients because of well-known dependencies within countries related
health systems etc. Also, the doctor's final word again is a matter of
his view, education
I also went to the following website and found the full text of the 1986

Please help me with the following Fortran program. When the line labeled
60 does not run, the result for q2 is correct; but when this line runs,
the results are totally wrong, since the values of z in the do-loop
change. Can someone tell why and how to correct it? Thanks in advance.

While not questioning your analysis, I
Provalis Research is pleased to announce the release of WordStat 3.0.
WordStat is a content analysis module specifically designed to analyze
textual information such as responses to open-ended questions, interviews,
titles, journal articles, public speeches, electronic communications, etc.
Arguments are always passed by reference in Fortran, so a subprogram can
change their values as seen by the calling program. If this is not desired,
the subprograms should not modify their arguments.

The Massachusetts Dept. of Education committed what appears to be a
howling statistical blunder yesterday. It would be funny if not for the
millions of dollars, thousands of hours of work, and thousands of
students' lives that could be affected.
Massachusetts has implemented a state-wide
Thanks everyone for your help. The problem is that the argument changed
in the function, a new feature for Fortran, but it gives me much troble.

Hello,
let's say I have a linear model such as:
yt = bt*Xt + et, where et ~ iid(0,se ^2)
and I want to introduce a specification that says that the parameters are
varying over time such as:
bt = b_t-1 + ut, where ut ~ iid(0,su^2)
with su and se different.
How to estimate such a
