negbin.regs: Many negative binomial regressions

In Rfast2: A Collection of Efficient and Extremely Fast R Functions II

Many negative binomial regressions

Description

Many negative binomial regressions.

Usage

negbin.regs(y, x, type = 1, tol = 1e-07, logged = FALSE, parallel = FALSE, maxiters = 100)

Arguments

y	The dependent variable, a numerical variable with non negative numbers
x	A matrix with the indendent variables.
type	You can choose which way your prefer. Type 1 is for smal sample sizes, whereas type 2 is for larger ones as is faster.
tol	The tolerance value to terminate the Newton-Raphson algorithm.
logged	If you want the logarithm of the p-values set this equal to TRUE.
parallel	Do you want this to be executed in parallel or not. The parallel takes place in C++, therefore you do not have the option to set the number of cores.
maxiters	The maximum number of iterations that can take place in each regression.

Details

Many simple negative binomial regressions with a log-link are fitted.

Value

A matrix with the test statistic values and their relevant (logged) p-values.
