Markov transition matrices , missing transitions for certain years
...working with is 125 boxes over 14
years that can be occupied by 7 different species, though I have provided a
slimmed down portion for this question...
-
A box can be in 1 of 4 "states" (i.e. bird species): 1,2,3,4
Included here are 4 "box histories" over 4 years (y97, y98, y99, y00)
These are the box histories
> b1 <- c(1,1,4,2)
> b2 <- c(1,4,4,3)
> b3 <- c(4,4,1,2)
> b4 <- c(3,1,1,1)
> boxes <- data.frame(rbind(b1,b2,b3,b4))
> colnames(boxes) <- c("y97","y98","y99","y00")
> boxes
y97 y98 y99...
