Hello again!

So, looking at the example in the cdf -help, I get:

ccalc -expr 'fitt_t2p(3,20)'
0.007076

which appears to be the two-sided p-value.

Is there a way to get the one-sided upper tail p-value?

Otherwise, I guess we need to write a function which assigns 1-half the current value if the t statistic is negative, and half the current value if the t-statistic is positive.

Many thanks again!

Best wishes,
Ranjan
