Minimizing a Function with three Parameters
Hi,
I'm trying to get maximum likelihood estimates of \alpha, \beta_0 and
\beta_1, this can be achieved by solving the following three equations:
n / \alpha + \sum\limits_{i=1}^{n} ln(\psihat(i)) -
\sum\limits_{i=1}^{n} ( ln(x_i + \psihat(i)) ) = 0
\alpha \sum\limits_{i=1}^{n} 1/(psihat(i)) - (\alpha+1)
\sum\limits_{i=1}^{n} ( 1 / (x_i + \psihat(i)) ) = 0
\alpha \sum\limits_{i=1}^{n} ( i / \psihat(i) ) - (\alpha + 1)
\sum\limits_{i=1}^{n} ( i / (x_i + \psihat(i)...

R-alpha: Mathematical Annotation in R (plots)
...l mathematical function of the corresponding name. Each
of these functions takes three arguments; the first indicates what
is being summed/multiplied/integrated and the second and third specify
the limits of the summation/product/integral. For example, {\tt
sum(x[i], i==0, n)} produces $\sum\limits_{i=0}^n x_i$.
\item[radicals] a square root expression is specified using the
special mathematical functions {\tt root} and {\tt sqrt}. For
example, {\tt sqrt(x)} produces $\sqrt x$.
\item[absolute values] an absolute term is specified using the
special mathematical function {\tt abs}....
