Re: [R] Difference betweeen cor.test() and formula everyone says to use

Hi Jeremy, I don't know about references, but this around. See for example: http://afni.nimh.nih.gov/sscc/gangc/tr.html the relevant line in cor.test is: STATISTIC <- c(t = sqrt(df) * r/sqrt(1 - r^2)) You can convert *t*s to *r*s and vice versa. Best, Josh On Fri, Oct 17, 2014 at 10:32 AM

Re: [R] evaluate NA to FALSE instead of NA?

Hi, Perhaps still not as short as you want, but I normally use which(): p <- c(1:10/100, NA, NaN) p[which(p <= .05)] [1] 0.01 0.02 0.03 0.04 0.05 Cheers, Josh On Tue, Oct 14, 2014 at 8:51 PM, Rainer M Krug wrote: > Hi > > I want to evaluate NA and NaN to FALSE (for indexing) so I would lik

Hi Stephane, This is the well known result of limitted floating point precision (e.g., http://www.validlab.com/goldberg/addendum.html). Using a test of approximate rather than exact equality shows R yields the correct answer: nperm <- 1 Fperm <- replicate(n=nperm, anova(lm(sample(Y) ~ F, dat

Re: [R] Is there a package for EFA with multiple groups?

Hi Elizabeth, In confirmatory factor analysis with multiple groups, the reason one needs to estimate the models simultaneously is that, typically, one is interested in applying constraints (e.g., forcing all or some of the factor loadings to be equal across groups). In exploratory factor analysis

Re: [R] Box-cox transformation

Hi Ravi, Deviance is the SS in this case, but you need a normalizing constant adjusted by the lambda to put them on the same scale. I modified your example below to simplify slightly and use the normalization (see the LL line). Cheers, Josh ## require(MASS)
