Hello
An agronomist conducted an experiment in Split - Plot Design wherein he
has taken 5 levels of irrigation as main plot treatments and 4 lelvels of
Nitrogeneous fertilisers as sub plot treatments. The experiment was
conducted over a period of 3 years with fresh randomisation in each year.
He desires to carry out the pooled analyis.
I request the members to suggest some suitable methods of analysis of
groups of such experiments under the following situations
(i) Main Plot Error variances Error (a) and Sub Plot error variances Error
(b) are homogeenous
(ii) Main Plot Error variances Error (a) homogeneous and Sub Plot error
variances Error (b) are heterogeneous
(iii) Main Plot Error variances Error (a) heterogeneous and Sub Plot error
variances Error (b) are homogeenous
(iv) Main Plot Error variances Error (a) heterogeneous and Sub Plot error
variances Error (b) are heterogeneous.
I further request the members to suggest some software ( free )
available on internet to tackle such situations.
