for loops
Hello everybody
I'm very new at using R so probably this is a very stupid question.
I have a matrix of "p" columns and I have to calculate for each of them the "two sample t-statistic" and p-value and to save the results into two different vectors.
I have divided my matrix into two submatrices: submatrix A containing the first "n1" rows (p columns) and submatrix B

Re : stat question - not R question so ignore if not interested
For the first question x'(y-bx)<>0 or Cov(Ui,Xi)<>0 you have heterogeinity problem !
OLS estimator in this case in biased.
The bias is equal to (Exx')^{-1}Exu
You obtain obtain correct estimator by use instrumental variable or 2SLS ...

Re : A smal fitting problem...
May be you are also not familiar with statistic. the solution of
min \sum_{i=1}^{n} (y_{i}-b)^{2} is the mean. So the solution is
b<-mean(y)

Have the counter function in R ?
if we use the software SAS

do i = 1 to 5;
call ranuni(seed,x);
output;
end;
run;
data new;
counter=_n_; ***** this keyword _n_ ****;
set tmp;
