[R] How fast is the JSS reviewing process?

Hi all, I thought I read somewhere that the reviewing process of the Journal of Statistical Software was quite fast (arround 3 month). Is that correct? -- Christophe Genolini Maître de conférences en bio-statistique Vice président Communication interne et animation du campus Université Paris

Re: [R] coxph with time-dependent covariates

R throws out this event due to the missing time-dependent covariate at day 6. Is there a way I can keep this event without filling in a covariate value at day 6? No. The Cox model assesses the risk associated with each covariate by comparing, at each event time, the values of the subject who

[R] Problems with table

Hi, I have 25 questions divided into 3 modules. I'm building tables of DISCIPLINE with each of the questions (Q1, Q2, Q3, ..., Q25). Each table, of course, has a different title. In the first module (questions Q1, Q2, ..., Q7) I don’t have problems with the titles of tables. DISCIPLINA -

[R] About Assigning Missing Values

Hi all,   I have a data set, named ‘data1.long’, which has 180 subjects with two variables, ‘time’ and ‘patient’. The ‘time’ variable takes 9 values, i.e., 1, 2, 3,…,9, and the ‘patient’ variable takes two values, 0 and 1. There are 10 subjects for each combination of

Re: [R] About Assigning Missing Values

Your assignment of NAs is fine. When you extract, you have to remember to specify whether you want to include or exclude those NA values. Try this: data1.long[data1.long$time==9 !is.na(data1.long$time), time] Jean On Tue, Jan 14, 2014 at 7:22 AM, Chia-Chieh Lin

[R] about linear model in R

Hello :) I'm Solip Park in Barcelona :) I have one question about linear model in R. I used generalized linear model (glm) in R with three variables (A,B, and C). So I made a model like this; glm.model = glm (Freq ~ A * B * C, family = poisson) and then, anova (glm.model, test = Chisq). It
