Mercury Concentration Analyzing
Budget: $10 – $30 USD
I need to analyze the mercury concentration in a group of fish with a dataset i collected using R.
Ideally the code will consider the concentration of mercury with a linear model that can account for the river effect, length and weight of the fish. Make sure you address issues if they are necessary, like variable transformation, interactions, and non-linear terms. Discuss your results and plot them.
2) Revisit the analysis of the mercury data (fish.txt) using an additive model and compare with the fit of the linear regression that you have obtained before
3) Fit a GLM for abundance from the goblinfish data. Use only the presence data for this particular case. Compare the fit and the results with a GAM
