replicates

Hi, I'm looking to carry out a study which will involve a pairwise choice comparison. I am aiming to identify any patterns of preference by wild individuals (measured by abundance) when presented with four different types of refuge. I will be conducting it in the form of pairwise choice...

Hi I'm really pretty lost, statistics have never been my strong point. I need to test whether my growth rate differences between trees are significant or not. I tried the ANOVA: 2 factor with replication on excel, but keep getting an error so I'm not sure if my data is suitable. SO first off...

Hi, Thanks in advance for any insight!

Hello - I conducted an animal survey along 4 transects (1000 m each) where I also measured and identified all of the trees. I then repeatedly sampled these 4 transects daily, counting the animals when they were encountered. What I want to do: Run a generalized linear mixed model where...

Hi, I have written 3way-anova in c++. I have 3 factors, lets say a,b and c. The result of my code is the same as MATLAB when I use type I sum of squares. But when I change the data so that the number of replicates is so high for a number of cells and too low for other cells: I don't get the...
