The formula for almost any roll is easily calculated as:

80% + 5%*(User's.stat - opposing.stat)

so, for example, a skeleton warrior attacks a swordsman. The skelly's accuracy is 9, and the opposing stat is the swordsman's parry, which is 11. the formula then reads as 80% + 5%*(9-11), which is 70% chance to hit. (this is why swordsmen are good).

In the case of the necromancer's incantation rolls, it is simple to calculate. A caster casts spells using their will stat compared to the spell's difficulty as the "opposing stat". So with the necromancer's Will of 14, the "respite of the dead"'s difficulty of 14, the formula reads as 80% + 5%*(14-14), or simply 80%.

This is affected by the necromancer's "Mastery of the arcana" ability, which adds 20% to the incantation roll, putting the roll at a nice even 100%. (I believe mastery of the arcana is the best choice on a necro that takes healing.)

Note that this is just the basics of calculating a roll. There are several other factors that can affect a roll, including, but not limited to, things such as encirclement or penalties associated with a non-warrior caster trying to cast a spell while engaged.
