gpuTtest: T-Test Estimator with a GPU

In gputools: A Few GPU Enabled Functions

Description

Given the number of samples and a Pearson correlation coefficient, this function estimates the t-score on a GPU. If an entry in goodPairs is zero or one then you may get a NaN as the t-test result.

Usage

	gpuTtest(goodPairs, coeffs)

Arguments

goodPairs	a vector of positive integer values. Value i represents the number of samples used to calculate the i-th value of the 'coeffs' argument.
coeffs	a vector of floating point values representing Pearson correlation coefficients.

Value

a vector of single precision floating point values. The i-th entry is an estimate of the t-score of the i-th entry of the 'coeffs' argument.

Examples

goodPairs <- rpois(10, lambda=5)
coeffs <- runif(10)
gpuTtest(goodPairs, coeffs)
