Re: [R] glm: modelling zeros as binary and non-zeroes as coming from a continuous distribution

Update: turns out there was a sister posting to mine two years ago: http://r.789695.n4.nabble.com/Zinb-for-Non-interger-data-td898206.html It was then suggested to use a zero-inflated distribution from the gamlss package. It turns out that they do have a zero-adjusted (albeit not strictly speakin

Hi Dennis, Thanks - these were the first things I tried, but the problem is that they refuse to work with non-count data... Mikhail On Wed, Mar 30, 2011 at 12:56 PM, Dennis Murphy wrote: > Hi: > > You might want to consider hurdle models in the pscl package. > > HTH, > Dennis > > On Wed, Mar 30,

[R] allEffects() with lm

is a bug or a "feature" and in the latter case, what can be done to display effects of the terms in a "combined" way, such that the contribution of both them on their own and as part of an interaction term is taken into account. Many thanks Mikhail -- Mikhail Spivakov, PhD Europea

[R] logistic regression

Hi everyone, I'm sorry if this turns out to be more a statistical question than one specifically about R - but would greatly appreciate your advice anyway. I've been using a logistic regression model to look at the relationship between a binary outcome (say, the odds of picking n white balls fro

[R] colorspace package does not compile on ubuntu 7.04 32 bit

don't really know how to resolve it. Any advice will be appreciated - or perhaps somebody has got this package compiled and could share the binaries? Many thanks! Mikhail Mikhail Spivakov, PhD European Bioinformatics Institute European Molecular Biology Laboratory Germany/UK * Insta

Hi Xavier, Changing the grid settings has worked! Thanks a lot! Mikhail PS Perhaps it'd still be really useful to be able to change text direction in labels. Hadley, what do you think? -- View this message in context: http://www.nabble.com/ggplo2%3A-x_discrete-labels-size-direction-tp1707747
