chi2Test: Chi-squared Test
In bips-hb/pvm: PharmacoVigilance Methods

Performs the chi-squared test with or without Yates's continuity correction to a collection of 2 x 2 tables of the form

	event	not event
drug	`a`	`c`
not drug	`b`	`d`

1	chi2Test(a, b, c, d, yates = FALSE)

`a`	A vector with the counts of the upper left corner of the tables
`b`	A vector with the counts of the lower left corner of the tables
`c`	A vector with the counts of the upper right corner of the tables
`d`	A vector with the counts of the lower right corner of the tables
`yates`	If `TRUE`, Yates's correction is used

p-value

The standard warnings for when the counts are too low in the 2 x 2 tables are suppressed. Due to the sparse nature of spontaneous reporting data, this happens quite frequently.
