Many exponential regressions

Description

Many exponential regressions.

Usage

expregs(y, x, di, tol = 1e-09, logged = FALSE)  

Arguments

y

A vector with positive data (including zeros).

x

A numerical matrix with the predictor variables.

di

A vector of size equal to that of y with 0s and 1s indicating censoring or not respectively.

tol

The tolerance value to stop the newton-Raphson iterations. It is set to 1e-09 by default.

logged

A boolean variable; it will return the logarithm of the pvalue if set to TRUE.

Details

We have implemented the newton-Raphson in order to avoid unnecessary calculations.

Value

A matrix with three columns, the test statistic, its associated (logged) p-value and the BIC of each model.

Examples

## 200 variables, hence 200 univariate regressions are to be fitted
x <- matrnorm(100, 100)
y <- rexp(100, 4)
expregs(y, x, di = rep(1, length(y)))
x <- NULL
