[R] LME and overall treatment effects

2011-07-14 Thread Mark Bilton
Hello fellow R users, I am having a problem finding the estimates for some overall treatment effects for my mixed models using 'lme' (package nlme). I hope someone can help. Firstly then, the model: The data: Plant biomass (log transformed) Fixed Factors: Treatment(x3 Dry, Wet, Control)

[R] likelihood

2009-05-22 Thread Mark Bilton
I have a problem related to measuring likelihood between -an observed presence absence dataset (containing 0 or 1) -a predicted simulation matrix of the same dimensions (containing values from 0 to 1) This must be a common problem but I am struggling to find the answer in the literature.

[R] Product of 1 - probabilities

2009-05-21 Thread Mark Bilton
I am having a slight problem with probabilities. To calculate the final probability of an event p(F), we can take the product of the chance that each independent event that makes p(F) will NOT occur. So... p(F) = 1- ( (1-p(A)) * (1-p(B)) * (1-p(C))...(1-p(x)) ) If the chance of an event within
