Dear All I am having problems to install the package COZIGAM. Despite I have the update version of R (3.0.2) when I try to load the package I cannot find it in the list of available packages. If I try to install it from a local zip file I do get this error message: Error in read.dcf(file.path(pkgname, "DESCRIPTION"), c("Package", &quot...

Hi All, Another quick question - I noticed that COZIGAM has been removed from CRAN, and that you are referred to the archive for previous versions (last updated 23 July 2012). Is this package still ok to use? Or is there an alternative which might also fit zero-inflated GAMs? Thanks, Raeanne The Scottish Association for Marine Science (SAMS) is regist...

...eventh through end of columns: frequencies of each respective insect counts. As you can see, I have data with extreme number of zeros in each year and by different insects. Even in 2000, there is no insect count at all. So, I tried fitting 'zero inflated Poisson model' to the data using cozigam function as follows: > chf.res1 <- cozigam(chafer ~ s(longitude, latitude) + s(PC1) + s(PC2) + s(PC3) + s(PC4) + (year) + paddock2, family=poisson, data=df.chf09) iteration = 2 norm = 1.023552 iteration = 3 norm = 0.4258558 iteration = 4 norm = 0.003208923 iteration = 5 norm = 0....

...sas-l&P=R20779, where they use NLMIXED (with only fixed effects) to specify their own log-likelihood function. I'm wondering if there's any way to do the same in R (lme can't deal with this, as far as I'm aware). Finally, I'm wondering whether anyone has experience with the COZIGAM package - does it do something like this? Many thanks, Mikhail

 Hello everyone, Apologies in advance, as this is partially a stats question and partially an R question.  I have been using a GAM to model the activity level of bats going into and coming out from a forested edge.  I had eight microphones set up in a line transect at each of eight sites, and I am hoping to construct a model for each of 7 species.  My count data has a reverse J-shaped skew and
