eturns the probability for the Student t-distribution where a numeric value is a calculated value of t for<br />

which the probability is to be computed. Value is the value at which you want to evaluate the distribution<br />

and must not be negative. Degrees_freedom is a positive integer stating the number of degrees of freedom.<br />

Tails must be either 1 (one-tailed distribution) or 2 (two-tailed distribution). All arguments must be numeric,<br />

else null will be returned. This function is related to the tinv (prob, degrees_freedom) (page 315) function<br />

in the following way:<br />

If prob = tdist(value, df ,2), then tinv(prob, df) = value.<br />

Example:<br />

chdist( 1, 30, 2 ) returns 0.3253086<br />

tinv (prob, degrees_freedom)<br />

returns the t-value of the Student's t-distribution as a function of the probability and the degrees of freedom.<br />

Prob is a two-tailed probability associated with the t-distribution. It must be a number between 0 and 1.<br />

Degrees_freedom is an integer stating the number of degrees of freedom. Both arguments must be numeric,<br />

else null will be returned. This function is related to the tdist (value, degrees_freedom, tails) (page 314)<br />

function in the following way:<br />

If prob = tdist(value, df ,2), then tinv(prob, df) = value.<br />

Example:<br />

tinv(0.3253086, 30 ) returns 1<br />

fdist (value, degrees_freedom1, degrees_freedom2)<br />

returns the F-distribution.. Value is the value at which you want to evaluate the distribution. Value must not<br />

be negative. Degrees_freedom1 is a positive integer stating the number of numerator degrees of freedom.<br />

Degrees_freedom2 is a positive integer stating the number of denominator degrees of freedom. All arguments<br />

must be numeric, else null will be returned. This function is related to the finv (prob, degrees_freedom1,<br />

degrees_freedom2) (page 315) function in the following way:<br />

If prob = fdist(value, df1, df2), then finv(prob, df1, df2) = value.<br />

Example:<br />

fdist( 15, 8, 6 ) returns 0.0019369<br />

finv (prob, degrees_freedom1, degrees_freedom2)<br />

returns the inverse of the F-distribution. Prob is a probability associated with the F-distribution and must be<br />

a number between 0 and 1. Degrees_freedom is an integer stating the number of degrees of freedom. All<br />

arguments must be numeric, else null will be returned. This function is related to the fdist (value, degrees_<br />

freedom1, degrees_freedom2) (page 315) function in the following way:<br />

If prob = fdist(value, df1, df2), then finv(prob, df1, df2) = value.<br />

Example:<br />

finv( 0.0019369, 8, 5 ) returns 15.0000197<br />

Financial Functions<br />

Note!<br />

For all financial functions it is vital that one is consistent about what units are used for specifying rate and<br />

nper. If monthly payments are made on a five-year loan at 6% annual interest, use 0.005 (6%/12) for rate<br />

and 60 (5*12) for nper. If annual payments are made on the same loan, use 6% for rate and 5 for nper.<br />
