...and stops doing it in half way through the data. I looked at the observation where reading stops, but it is really not different from the observations read it. I expanded the matrix size, but it did not help. I am using a text format to read the data file. Could someone help me? Thank you Soyoko

Hi, I would like to know if anyone has any idea of how to run an OLS with constraints? I need to contraint a coefficient estimate in the model equal to 1, and I am not sure how to include it into the OLS estimation... I was hoping to find something like "cnsreg" in STATA.. thank you Soyoko ______________________________________ Ms. Soyoko Umeno Graduate Research Assitant for the Illinois-Missouri Biotechnology Alliance (IMBA) at http://www.imba.missouri.edu/ Ph.D. Student at the Department of Agricultural and Consumer Economics at the University of Illinois at Urbana-Champaign Offic...

...t;- format(ex, "%d%b%Y") > ez-z Error in ez - z : non-numeric argument to binary operator As you may see, I am getting an error. Can anyone tell me how I can convert z and ez to numeric vectors, so that I can compute days between the corresponding dates in these vectors? thank you soyoko ______________________________________ Ms. Soyoko Umeno Graduate Research Assitant for the Illinois-Missouri Biotechnology Alliance (IMBA) at http://www.imba.missouri.edu/ Ph.D. Student at the Department of Agricultural and Consumer Economics at the University of Illinois at Urbana-Champaign Offic...

...les, c is the constant estimate, and a and b are the coefficient estimates. Then, I want to know the variance of b*c/a (2). How am I going to get it? In Stata, I can just use "bs" function by defining the regression model (1) and the statistic of the interest(2). Help!!!

...,y2, ann=FALSE, xaxt="n", yaxt="n", pch=7 ) axis(4) Then, I want to label the second y axis "pay2". I tried "title(ylab="pay2")", but it put this lable on the first y-axis. Does anyone know how to move this to the second y-axis?

Hi, I would like to know if anyone knows how to draw a plot with two Y-axises and one X-axis? When you have two sets of y values that do not have the same scale, but correspond to the same x value, I would like to plot them on one graph. Could you please help me? Thank you Soyoko
