# Generate delta matrix

### Description

This function will generate the matrix of deltas, as specified in the paper. See Details section.

### Usage

1 | ```
genDelMat(theta.diff, sigma.2 = 1, n = 1)
``` |

### Arguments

`theta.diff` |
A vector of length p-1, where p is the number of populations
of treatments. Coordinate [i] in theta.diff corresponds to |

`sigma.2` |
The known variance of the error terms. |

`n` |
The number of replications in each population. |

### Details

As specified in the paper, we can assume that the thetas are in a
decreasing order, meaning that *θ_1 ≥ θ_2, …, θ_n*.
It follows that all the components of the theta.diff vector must be positive.
Note that the delta matrix in the paper is a scaled version of the
differences between the thetas.

### Value

The function returns a matrix with p rows and p columns, that
contains the *delta_{ij}*'s, as described in the paper.
