Result
Writes text on graph beginning at pixel (row,column), where
0  row  57 and 0  column
Sets sequence graphs to plot with respect to time.
Converts seconds to units of time that can be more easily
understood for evaluation. The list is in
{days,hours,minutes,seconds} format.
Computes a t confidence interval.
Computes a t confidence interval.
Computes the probability density function (pdf) for the
Student-t distribution at a specified x value with specified
degrees of freedom df.
Displays the graph and enters TRACE mode.
Performs a t test with frequency freqlist. alternative=
alternative=0 is ƒ ; alternative=1 is >. drawflag=1 draws
results; drawflag=0 calculates results.
Performs a t test with frequency freqlist. alternative=
alternative=0 is ă ; alternative=1 is >. drawflag=1 draws
results; drawflag=0 calculates results.
Computes the future value.
Computes the annual interest rate.
Computes the number of payment periods.
Computes the amount of each payment.
Computes the present value.
