accum_test: Accumulation test with the hinge-exponential function
In stephenbates19/digitaltwins: Causal inference for SNPs

Takes an ordered list of p-values and returns a set of selections controlling the false discovery rate. This is an implementation of the method of Li and Barber, JASA 2017.

1	accum_test(x, alpha = 0.2, c = 2, strict = FALSE)

`x`	A vector of p-values to be tested IN ORDER.
`alpha`	The desired FDR threshold.
`c`	Parameter of the hinge-exponential function used in the test.
`strict`	If TRUE, the procedure is more conservative but controls the false discovery rate. If FALSE, the procedure is more liberal but controls a modified version of the false discovery rate.
