Answer to Question #37591 in Other Programming & Computer Science for Jason

Question #37591
I need to write a program that does the following in R: I have a data set (42 rows, 2 columns) of y variables and x variables. I want to randomly select 12 rows from this matrix and record the coefficients (slope and intercept) of a linear regression of the randomly generated matrix. I would also like to write a loop for this so I can repeat this 1000 times, so I can then have a matrix with 1000 rows and 2 columns filled in with the slopes and intercepts of the 1000 randomly selected sets of 12 rows from my data set. I am able to get this far but do not know how to incorporate a loop into the code, and a way to store the coefficients into a a matrix. # Box.Z and Box.DC.gm are columns of data used to generate my initial matrix of data A <- matrix(c(Box.Z, Box.DC.gm), nrow=42) B <- A[sample(42, 12), ] C <- lm(B[,2] ~ B[,1]) D <- matrix(c(coefficients(C)), ncol =2)
