Dear R-helpers, I'm for sure not familiar with R, but it seem like a nice sofware tool, so I've decided to try using it. Here is my problem I just can't figure out: I'd like to do least square fit of a straight horizontal (a = 0) line y = ax + b through some data points x = (3,4,5,6,7,8) y = (0.62, 0.99, 0.83, 0.69, 0.76, 0.82) How would i find b????? All the best, Ked

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 ... Justin BEM Elève Ingénieur Statisticien Economiste BP 294 Yaoundé.

Hi all! I've got a datstructure like this: subject week value 1 1 4 2 1 8 3 1 3 4 1 5 1 2 5 2 2 6 3 2 2 4 2 6 1 3 3 2 3 7 3 3 3 4 3 7 I'd like to plot the mean of 'value' against week. Is there a direct way of doing this or do I have to make a new structure with the calculated values and then plot it? All the best! -- ########################################### Kare

I'm writing an publication in two column format and need to shrink some plots. After increasing the axis labels it does not look nice at all. The y-axis label and tick labels almost touch each other and the x-axis tick labels expand into the plot instead of away from it. Is there a better way than "cex" to control the: 1) font size of axis and tick labels 2) font thickness 3)
