I am using ddply on a data set that contains 2+ million rows; trying to rank
the values of a variable within groups, and then transform the ranks to
(approximate) z-scores --- i.e generate quantiles on the normal scale.
Here is some sample data for one group:x <- NA 0.3640951 0.1175880 0.3453916
What is the code in R to get the goodness of fit in nls?? Please sir...

Hi all;
I have a big data set (a small part is given below) and V1 column has repeated
info in it. That is rs941873, rs12307687... are repeating many times. I need
choose only one SNP (in first column named rs) which has the smallest Pvalue

A quick (I think) question.
Does the survreg() function in the survival package handle Surv()
objects of type mstate?
It's not clear from the documentation that it doesn't. The Vignette only
discusses the Cox model and the Fine-Gray model.
I tried using survreg() on an mstate Surv() object.

Dear Michael F
What you say is of course true but Michael E (or possibly Simone) seems
to be using a function glht from an unnamed package. Since we do not
have the data or the offending output it is hard to be sure though.

Dear Michael and Michael,
I took a quick look at the Statistica website, and their definition of "types"
of sums of squares doesn't appear to be the same as the common definition,
which originated with SAS. As I read their materials, what they call "Type VI"

Don,
Thank you for your helpful response. At this point, I do believe it is a
package error and I have contacted the developer.

Use car::Anova() for type II and type III sums of squares and F-tests.
The sequential type I tests computed by anova() are rarely sensible

Hi all,
I hope you are doing well?
I'm currently using lm() to estimate a linear multi-factor (5 factors without
intercept) model as follows ...
factor.lm <- lm(y~x1+x2+x3+x4+x5-1, data = data.frame.rbind)
Using nnls(A,b) I estimated the same model, extended by a non-negativity
