 
  Hello,
 
1)  I am interested in performing a limited-dependent variable linear regression.  By this I mean a classical linear regression, but for the case where the values of the dependent variable cannot vary from -infinity to +infinity, but are truncated and so are between two finite limits L1 and L2.  Does R1.7 have this capability?  If so what is (are) the relevant command(s)?
 
2)  I am also interested in sampling from a multivariate normal distribution.  I see that R has a command mvrnorm, but when I try to use it, I get a message to the effect that the command is not recognized.  Is there something I must do to enable this command, or is it not available in version 1.7?

  Thanks,
 
  Howard
