4.2 Estimating the Coefficients of the Linear Regression Model.

I will include this in case … "MLF" : for maximum likelihood estimation with standard errors based on the first-order derivatives, and a conventional test statistic.

I've included a picture of the formulas for the estimate and variance.

Therefore, we must employ data to estimate both unknown parameters. (Hint: The Chao2 index works with presence/absence data, so convert your bird matrix into binary using the code birds[birds>0] = 1.
