Use \genfrac command for binomial coefficient in LaTeX. amsmath package contains an interesting command. In the first two arguments, you have to use left and right parentheses. And lastly, two arguments of binomial coefficient have to be used.

Este tutorial explica cómo trabajar con la distribución binomial en R usando las funciones dbinom, pbinom, qbinom y rbinom.. dbinom. La función dbinom devuelve el valor de la función de densidad de probabilidad (pdf) de la distribución binomial dada una determinada variable aleatoria x, número de ensayos (tamaño) y probabilidad de éxito en cada ensayo (prob).
dnbinom computes via binomial probabilities, using code contributed by Catherine Loader (see dbinom). pnbinom uses pbeta. qnbinom uses the Cornish–Fisher Expansion to include a skewness correction to a normal approximation, followed by a search. rnbinom uses the derivation as a gamma mixture of Poissons, see Description. Calculates exact p-values and confidence intervals for a single binomial parmeter. This is different from binom.test only when alternative='two.sided', in which case binom.exact gives three choices for tests based on the 'tsmethod' option. The resulting p-values and confidence intervals will match.
1. I am using dnbinom () for writing the log-likelihood function and then estimate parameters using mle2 () {bbmle} in R. The problem is that I got 16 warnings for my negative binomial model, all of them NaNs produced like this one: 1: In dnbinom (y, mu = mu, size = k, log = TRUE) : NaNs produced. My code:

I would like to calculate the log-likelihood "by hand" (in R, but without use of the logLik function) based on the estimated parameters obtained from gnls so it matches the output from logLik(fit).
