article by Kruglyak, Nickerson on the effect of SNP frequency on the LD and a measure of frequency matched SNP correlation.

linear trend ordinal variables

linear trend test for dichotomous(binary) with categorical-ordinal variables
e.g. linear trend of risk (OR) of some disease across genotypes

Cochran-Armitage - in SPSS can be done as - sort of - CROSSTABS - linear-by-linear association

ANOVA, permutation test, in R

while searching for a code in R to run a permutation test on ANOVA (eg. genotype - continuous variable association, adaptation of p values etc.) I found the following resources valuable:

some resources on ANOVA calculation in R and permutation test when comparing multiple groups (more than two)

mrpp function in vegan package seems to be appropiate (as an alternative to permutation test and comparison of F-values), cf measures of distance (euclidian, delta etc.)
MRPP stands for
Multi Response Permutation Procedure of Within- versus Among-Group Dissimilarities

certainly a comprehensive resource on ANOVA in R is
Faraway´s: Practical Regression and Anova using R (pdf) 200+ pages

very nice intro in ANOVA 3pp (pdf)

site by the Dutch Guido W to accompany some textbook by neter (1996), but nevertheless seems informative/instructive

(((((((( what is this about?????))))))
voila: fast introduction to the concept of resampling, randomization (and permutation) tests, bootstrapping can be found on pages of David Howell. david also provides a free software, which is very easy to install, use and understand. However, it may not be used for publications, as the algorithms is not clear etc. Anyway, a very nice site and software.
check david howell´s site here.
other resource is the freely available book (pdf) of Simon´s book - e.g. on statistics.com



les examples utiles de code en R pour les analyses simples je trouvait sur la site de Christian Jost dans le cadre de ses courses
