long time for execution

    This takes me back to listening to a professor lament about the researchers that would spend years collecting their data, then negate all that effort because they insist on using tools that are quick rather than correct.

    So, before dismissing the use of pvals.fnc you might ask how long it takes to run relative to how long it took to collect the data and the importance of the answer. If you feel the need to compute p-values multiple times, then you may need to rethink your approach (model selection based on repeated p-values results in p-values that are meaningless at best).

    If you consider the above and still feel the need for a quick p-value rather than a correct one then you can use the SnowsCorrectlySizedButOtherwiseUselessTestOfAnything function from the TeachingDemos package. It is quick (but be sure to fully read the documentation).
