Matrix/dataframe indexing
Hi all,
I am hoping someone can help me out with this:
If I have dataframe of years and ages and the first column and first row
are filled with leading values:
Df<- age1 age2 age3
Yr1 1 0.4 0.16
Yr2 1.5 0 0
Yr3 0.9 0 0
Yr4 1 0 0
Yr5 1.2 0 0
Yr6 1.4 0 0
Yr7 0.8 0 0
Yr8 0.6 0 0
Yr9 1.1 0 0
Now the rest of the cells need to be filled according to the previous
year and age cell so arbitrarily, cell [2,2] should be value in cell
[1,1] * exp(0.3), and cell [2,3] should be the value in cell [1,2]*
exp(0.3), etc.
How...

Simulation help
...trend. I've been
using the following code:
patBdta1 <- NULL
for(i in 1:100)
patBdta1 <- rbind(patBdta1,c(yr1= mean(rbinom(50,1,.50)),
yr2 =mean(rbinom(50,1,.51)),
yr3 =mean(rbinom(50,1,.52)),
yr4 =mean(rbinom(50,1,.53)),
yr5 =mean(rbinom(50,1,.54))))
This code creates 100 data sets each with a 5 yr binomial trend profile
with a slope of approximately .01.
Now, what I want to do is pass this code (or some code) in such a way
that I can simulate various t...
