cbse schools near sarjapur road
by foundationschoolindia＠gmail.com
The Foundation schools were established in 2009. The Gunjur branch has become one of the top CBSE schools in varthur, Gunjur, Whitefield and best school in Sarjapur Road areas in a short period of time. The schools follow a methodology that helps children through hands on activities and experiential learning. Children at The Foundation School are seen not as consumers who need external entertainment, but as producers who interact with various learning material with their own hands; construct knowledge and gain immense satisfaction from the process. In keeping with this methodology, The Foundation School follows the Montessori Philosophy at the pre-primary level, and experiential learning from grade 1 onwards. All of these make The Foundation School, one of the foremost leading and progressive schools in Varthur, Gunjur, Schools in Whitefield and also schools near sarjapur Road areas of Bangalore.

Re: fcast behavior
by ΑΝΔΡΕΑΣ ΖΕΡΒΑΣ
Many thanks Artur,
However, I was puzzled mostly by the different behavior of different
versions, in a case that seems to me they should behave in the same
manner. In any case, I have another question: if one modifies the model
so that there is no dynamic behavior, the --static option still gives
one period forecast, though it is not strictly necessary. It is
documented behavior, but is what one would expect? Your modified example
is attached (test_fcast2.inp).
Concerning the original example, in test_fcast3.inp (attached), I have
increased the out of sample forecast period to 10 periods. In 2019a
version the script works, in 2019c not (now on Win 10 both, though I
think the OS is irrelevant). I am assuming that all forecasts are
constructed in the correct way, i.e. using the last period forecast as
the lag of the endogenous variable from the second forecast period
onward. What created the difference?
Many thanks again,
Andreas

Request for cdemean()
by Stefano Fachin
dear all,
I think adding this to the GUI and extend it to operate on lists is a
great idea. We should be careful about definitions, though -
"standardize" means "center on the mean AND divide by standard
deviation". Probably something more neutral like "scale" or "rescale" is
more suitable for a function which can be flagged to either center only
or center + divide by s.d. (with or without d.f. correction)
thanks
Stefano

fcast behavior
by anzervas
Hi all,
I am attaching a small script showing unexpected (at least to me)
behavior of the forecast command. The script works in Gretl 2019a (in
Ubuntu 19:04) but not in 2019c (in Win 10).
Kind regards,
Andreas

Re: Request for cdemean()
by Ioannis A. Venetis
Personally I also agree with Stefano (something like rescale or rescale
itself). Of course in this case - strictly speaking - the demeaning
option is not rescaling.
I agree with Jack that maybe recursive demeaning goes a long way (let
alone rolling ;) ). But...
_I wouldn't endow a function with too many options, I find that very
R-ish,_
_but maybe it's just me. Anyway, recursive demeaning (that I have never_
_seen used anywhere, I'd be curious to see a real-life use case) is
easy_
_enough to do in hansl:_
_<hansl>_
_X = mnormal(20,3)_
_M = X - cum(X) ./ seq(1, rows(X))'_
_</hansl>_
Jack (and anyone interested in), have a look in section 3.2, p.585
Michael W. McCracken & Serena Ng (2016) FRED-MD: A Monthly Database
for Macroeconomic Research, Journal of Business & Economic Statistics,
34:4, 574-589, DOI:
10.1080/07350015.2015.1086655
This (recursive standardization) is a feature that I would like to see
in the staticfactor package and at a later stage in the DFM package
(just to replicate some of those results as in McCracken). Of course, I
am not sure (because i have not given a thought) about the theoretical
arguments that would support Principal Components estimation or other
estimators on recursively demeaned and/or standardized data (moment
conditions, consistency, convergence rates).
Apparently, I had - slightly changed - the source code in staticfactor
package quite a while ago to replicate the papers diffusion index.

Re: Request for cdemean() on lists (GUI appearance as well)
by Ioannis A. Venetis
I would also go for
=========
stdize
Output: same as input
Arguments: X (matrix or list)
dfcorr (integer, optional)
dfcorr = 0 (MLE)
dfcorr = 1 (sample standard deviation)
dfcorr = k > 1 (other)
dfcorr = -1 -> centering only
=================
with default k=1. Excellent.
Help remark:
"Returns the standardized version of the data contained in X, scaling
each series/column by the sample standard deviation (dfcorr = 1 by
default). For dfcorr = -1 each series/column is centered around its
sample mean (no scaling)
PS = What about inserting it in the menu? (Add)

Request for cdemean() on lists (GUI appearance as well)
by Ioannis A. Venetis
Hello all,
I do not know if it has been discussed previously...
but I would like to see the cdemean() function applied to lists and why
not (for teaching and general utility) as a menu item below (e.g) the
"Add" --> 100-based indices of selected variables under the name
"Standardize variables"?
P.S = of course I will not do the hard work ...
Thanks

Off-topic: cubes of primes
by Riccardo (Jack) Lucchetti
Ok, this is so offtopic that is nearly embarassing, but here goes.
I found on the net the attached picture (quite amazing in itself), so I
thought it'd be nice to write a hansl script to reproduce it. It turns
out the the little script below showcases quite a few features hansl has
(eg recursion, logical operators etc), so it could maybe be useful to
people who are teaching/learning Hansl. Enjoy!
<hansl>
set verbose off
function matrix prime_sieve(scalar n)
x = floor(sqrt(n))
c = seq(2,n)
prime = ones(1,n-1)
loop i = 2 .. x --quiet
prime[i+1:] = prime[i+1:] && !(c[i+1:] % i .= 0)
endloop
return selifc(c, prime)
end function
function scalar droot(scalar x)
y = floor(x)
ret = 0
loop while y >= 1 --quiet
ret += y % 10
y = floor(y/10)
endloop
if ret > 9
ret = droot(ret)
endif
return ret
end function
x = prime_sieve(200)
loop i = 1 .. nelem(x) --quiet
c = x[i]^3
printf "%5d: %5d\n", x[i], droot(c)
endloop
</hansl>
