I have two vectors as follows:
popd = vector(mode='numeric', 100)
popr = vector(mode='numeric', 100)
These represent the initial distribution within 2 populations.
I want to define these e.g.
These populations will then transform according to the following...
I'm trying to have R go through a loop within ID groups, and within each group:
- find the max year;
- count the number of prior observations (by year) that have a code other than the code corresponding to the current row;
- disregard observations that appear in the same year.
I would very...
I have a long vector of financial time series information, price and volume. I expand the price vector based on the volume vector so I essentially get a price per share traded, and so only one vector is analyzed.
I would like to split this vector into lengths of 17500 each, and apply the...
I am trying to create a matrix of the conditional probabilities from this:
Signal <- runif(100)
PercChange <- abs((rnorm(100)/100))
signalt <- seq(0, 1, 0.05)
abst <- seq(0, c(0.02:1), 0.0025)
CondDistMat <- matrix(0, nrow = length(signalt), ncol = length(abst))
So I've made a long do-file and I was wondering if there were a clever way to repeat parts of the do-file with a few changes? I'm doing a series of cross-national tests and I want to see what happens if I drop a single country and run all the tests again.
Basicly I want this...
