change likelihood function in survreg
Dear R users,
I'd like to fit different longevities for males and females (µm vs µf below) with a Weibull interval-censored survival model.
Unfortunately more than 50% of the individuals in the experiment died before their sex could be assigned.

Plot Moran's I
Hello all,
I'm a new user of R and I have used the spdep package to calculate Moran's I estimates. I used the dnearneigh() function and moran.test() function and obtained what I wanted, but now I want to plot my results with the p-values. I regrouped my results for the Moran's I like
>m=c(m1$e,m2$e...) #m1 contain the results of the moran.test for lag1

Weibull survival regression model with different shape parameters
Dear R users,
I'm trying to fit a parametric survival model using the survreg function
with a Weibull distribution.
I'm studying the time to death of individuals from different families
and I would like to fit different shape parameters (ie 1/scale in R) for
each of the families. I looked it up in the help pdf and on the
internet, but I couldn't find anything.
