nonparametric logistic regression based on locally weighted scatterplot smoothing (lowess)
Dear UseRs:
Recently, I have read an article regarding the association between age and
lymph node metastases.
http://jco.ascopubs.org/content/27/18/2931.long
In statistical analysis, the authors stated "Because a nonlinear
relationship between age and lymph node involvement was expected based on
existing literature, lymph node involvement was also regressed on age using
nonparametric...

An infinite recursion error please explain!
Probability <- function(N, f, w, b, y, t, q) {
#N is the number of lymph nodes
#f is the fraction of Dendritic cells (in the correct node) that have the
antigen
#w is time in terms of hours
#b is the starting position (somewhere in the node or somewhere in the gap
between nodes. It is a number between 1 and (x+t))
#y is the number of time steps it takes to traverse...

Confused about multiple imputation with rms or Hmisc packages
...arrell's book, this is what I've been toying with:
#recurfree_survival_fromsx is survival time, rf_obs_sx codes for events as a binary variable.
#The CPH model I would like to fit, using Ograde_dx as the variable for overall grade at
#diagnosis, ord_nodes as an ordinal variable for the # lymph nodes involved.
obj=with(mydata, Surv(recurfree_survival_fromsx,rf_obs_sx))
mod=cph(obj~ord_nodes+Ograde_dx+ERorPR+HER2_Sum,data=mydata,x=T,y=T)
#Impute missing data
mydata.transcan=transcan(~Ograde_dx+tumorsize+ord_nodes+simp_stage_path+afam+
Menopause+Age,imputed=T,n.impute=10)

Why does the graph converge?
I have a set of functions:
Probability <- function(N, f, w, b, l, n, q) {
#N is the number of lymph nodes
#f is the fraction of Dendritic cells (in the correct node) that have the
antigen
#w is time in terms of hours
#b is the starting position (somewhere in the node or somewhere in the gap
between nodes. It is a number between 1 and (x+t))
#q is the length of the time step
#l is the LN tran...

Compiling with GCC on win32?
Why does the source use `int64_t'. Is this suppose to be built
with GCC? I have Mumit Kahns gcc, version 2.8.1. Do I need a
2.9.5 version to get the `int64_t' type? I have substituted a
typedef of `long long' in os_types.h. This seems to make sense?
The rint() macro also seems to be having some problems. I guess
there are two meanings to __GNUC__ and _WIN32. One is the OS and
