Statistical inference for on-farm experiments
with focus on large strip trials
Dr Suman Rakshit
SAGI-West, School of Molecular and Life Sciences, Curtin University
On-farm experimentation on large strips are becoming increasingly popular in Australia. Two questions of interest are (i) what is the overall best treatment and (ii) does the treatment effect change in different parts of the field? The first question can be answered assuming spatial invariance of the treatment effect, however, the efficiency of the inference is greatly increased by considering the correlation in the yield data recorded by the sensor inside the combine harvester. We describe a two-stage Monte Carlo method for answering the first question. This method is shown to perform better than the existing asymptotic method which is shown to be anti-conservative in simulations. The second question is answered adapting methods available for local modelling of the spatial relationships. The theory of local likelihood is used to make formal statistical inference.
ABOUT THE SPEAKER:
Dr. Suman Rakshit is currently working at SAGI-West, Curtin University, as a Biometrician, where the core focus of his research is to develop experimental design for agricultural field trials and analysis of the trial data using advanced statistical techniques such as linear mixed model, factor analytic model and spatial variogram modelling. The other area of his research focus is genome wide association study for the analysis of quantitative traits of germplasms based on the maps of genetic markers.
Suman has also worked as a Data Scientist for the Horizon Power and Prima Consulting before joining SAGI-West. He spent 4 years as a post-doctoral researcher under Prof. Adrian Baddeley and Dr. Gopalan Nair, researching on the topics of spatial statistics. He has published several articles in the field of spatial statistics and developed an R-package for analysing point patterns on a linear network. He received his PhD in statistics from Monash University and master’s degree in statistics from Indian Institute of Technology, Kanpur.
Members and guests are invited to mingle over wine and cheese from 5:30 p.m. onwards in the Ross Lecture Theatre, University of Western Australia. Following the meeting you are invited to dine with the speaker at Steves, 30 The Avenue, Nedlands. Visitors are welcome.
PLEASE RSVP for the post-meeting dinner to Mario D’Antuono via email email@example.com or via mobile phone (0480 123 071) by 12 noon Monday August 12. The evening will include complimentary first drink, and coffees/cake for dessert on behalf of the two societies.
The Cheryl Praeger Lecture Theatre is located on the ground floor of the Mathematics building at UWA. The entrance is on the outside of the building and next to the Blakers Lecture Theatre. Note that UWA maps has this venue marked as Maths Lecture Room 1.
Parking is free on the UWA campus after 5pm.
