search for: comparissons

Hi Folks, I have been using the TukeyHSD to conduct post hoc comparisons. The challenge is I have two interacting factors, one of which has 6 levels (cover types), and the other 2 (study areas). As a result interpreting the post hoc comparisons is difficult when you get a list of every possible combination (66 of them). In grad school I was using SAS and I recall most of the post hoc tests

Greetings I'm a total newbie in R and I'm trying to make a comparisson of Excel and R in the fields of: - optimisation modeling (using solver) - decision trees - simulation modeling as described in Winston, Wayne L.: Practical Management Science. for optimisation modeling in Excel I would normaly use solver. In R however I can't seem to be able to find the solution. I've

Is there a way to cancel a specific effect? For instance; Effects are added to the queue. Before actually processing the effect, I''d like to check a condition & cancel the effect if necessary. Here''s the code excerpt: var menu = { toggleText: function(element,toggle) { var vis = $(element+''Text'').visible(); if (toggle && !vis)

..., comparing differents pairs with Man- Whitney (wilcoxon function in R) with a bonferroni correction for multiple comparisons. But as the data are in the percentaje form, I know I need to analize them with either a chi squared or a g-test, but I have no idea if I can do such a test with many comparissons or how to do it in R, as well I have seen a paper in which they do something similar and they are using a Harber's chi squared test. Does anybody know how to do that in R? Thank you very much for your help, and thanks to the jim and chuck for answering my previous statistical question...

Hello I've looked into SPEEX SDK and source codes provided on site www.speex.org , and I'm trying to include in my Visual Studio 2005 - Visual C++ SmartDevice WM 5.0 the facilities provided by SPEEX (both encoding/decoding).I've downloaded the header files (i.e. Speex.h Speex_bits.h etc) and also the libspeex.lib.After creating my encoding/decoding functions following the

Rob J Hyndman gives great explanation here (https://robjhyndman.com/hyndsight/estimation/) for reasons why results from R's arima may differ from other softwares. @iacobus, to cite one, 'Major discrepancies between R and Stata for ARIMA' (https://stackoverflow.com/questions/22443395/major-discrepancies-between-r-and-stata-for-arima), assign the, sometimes, big diferences from R

Che face? :) I suspect you should build your own .lib file - not use the pre-existing one. ________________________________ From: speex-dev-bounces@xiph.org [mailto:speex-dev-bounces@xiph.org] On Behalf Of Alex Lupoian Sent: Tuesday, March 14, 2006 10:34 AM To: speex-dev@xiph.org Subject: [Speex-dev] Windows Mobile 5.0 SDK - SPEEX Hello I've looked into SPEEX SDK and source codes

line 212 of postgresql_adapter.rb is return Time.now.to_s if value =~ /^\(''now''::text\)::(date|timestamp)/ i don''t think this will work. in postgresql the field ''now'' is pinned to the SAME TIME for the duration of a transaction. eg. if you do begin transaction; insert into t values(42, ''now''); # sleep one minute
