you will apply nonlinear modellingto physiological data collected on three NZ tree fern species (cyadea =Cyatheadealbata, cyasmi = Cyathea smithii, dicsqu= Dicksoniasquarrosa) . The data was collected with a fluorometerinstrument which was used to measure the electron transport rate in photosystemII (etr) (a proxy for photosynthesis) as a function of light (par).Please find the data in [login to view URL] data set. There were three individuals of each species (ind) and those are true statistical replicates, so no need to aggregate the data in this case. You will see that the etrdeclines at high light levels indicating photoinhibition. Use the attached self-starter function of theEilers& Peeters(1988) photosynthesis model, whichaccounts for this photoinhibitoryeffect. Run a varying coefficient model allowing individual parameter estimates for each tree fern species. Check the model assumptions and apply variance modelling techniques if required. Then formulate a model with common parameter estimates for all species using the same variance structure as in the varying coefficient model and compare the two models using a likelihood ratio test. If the varying coefficient model is supported by the likelihood ratio test, follow up with apost-hoccomparison using the attached custom pwcfunction (you also find the code for this function in the nonlinear regression course PDF). I will provide more details on chat.

I have experience using R for statistical analysis and machine learning and have worked on various data science projects such as recommender systems with NLP components, data mining with associative rules, etc. I also have a background in systems administration meaning that setting up, configuring and maintaining such systems as Hadoop environments, Spark clusters and cloud services are part of my forte. This means that I am able design and implement complex data science pipelines quite efficiently. Thus, I believe I am a good candidate to assist you with your tasks. Hoping to work with you on this project.

In order to fulfill the objective of my project, I will first categorize the variables into topics such as economy, education, and gender equality. Then I will use regression to determine whether cultural tightness influences people’s values and beliefs on these topics. Data filtering, regression, and visualization will be employed in my projects.

I'm a statistician working on the data analysis to accomplish clear and useful designs, conclusions and evidence of the data I'm interested in. R is the best programming language for me to analyze and apply the different tests such as t-test, F-test and chi-square test, as well as regression on the data I have. In addition, I have a minor in health statistics (Medical Statistics and epidemiology) and I apply my experience in the health researches, bioinformatics and health management as well.
