Probability functions return probabilities based on various distributions, such as the probability that a value from Student's t distribution will be less than a specific value.

Function Result Description
cdf_chisq(NUM, DF) Real Returns the probability that a value from the chi-square distribution with the specified degrees of freedom will be less than the specified number.
cdf_f(NUM, DF1, DF2) Real Returns the probability that a value from the F distribution, with degrees of freedom DF1 and DF2, will be less than the specified number.
cdf_normal(NUM, MEAN, STDDEV) Real Returns the probability that a value from the normal distribution with the specified mean and standard deviation will be less than the specified number.
cdf_t(NUM, DF) Real Returns the probability that a value from Student's t distribution with the specified degrees of freedom will be less than the specified number.
