Generic function to predict the cdf (cummulative density function) of continuous (e.g. size) stage at t+1 given stage at t and a growth object.

size |
vector of current sizes. |
sizeNext |
vector of sizes in the next time step. |
cov |
covariate level in this time step (numeric of length 1). |
growthObj |
a growth object. |
a vector of length sizeNext giving the cdf (cummulative density function) of each value of sizeNext.
