Probability Density Function
The F distribution is the ratio of two chi-square distributions with degrees of freedom and , respectively, where each chi-square has first been divided by its degrees of freedom.

If you look at the probability density function, you can see that that the term x- must be greater than 0. In most cases, the location parameter (theta) is known (usually 0): it identifies the smallest possible failure time.

[2] In order to construct predicted values for an output variable y from an input variable x, the modelling and calibration procedure arrives at a joint probability density function, p(y,x).

in which a Riemann-Stieltjes integral is used. For an absolutely continuous probability distribution with probability density function f, we have ...

Even before integrating, the answer was obvious: Gallistel finds that the posterior probability density function of the null hypothesis mimics the likelihood function of the data almost exactly.
