Dear all,
I have a blocking and nested design.
I have Season (3 levels; three different collection periods). That's my
Block.
I have three Populations that I sampled from (Plant material)
>From each population, I sampled 30 trees.
Each Tree is either Female or Male or Unidentified (Sex factor) and
Each tree is either Juvenile or Mature or Old (Maturity factor)
Maturity factor and Sex factor is not balanced within the population.
So, Population is nested within Sex and Maturity
I measure a chemical from the leaves of those trees with the name of PAC.
Is the way that I write the code correct?
lm (PAC ~ Season + Population+ Sex/Population + Maturity/Population)
Thanks a lot,
Eleftheria
