WebIn probability theory, a probability density function ( PDF ), or density of a continuous random variable, is a function whose value at any given sample (or point) in the sample space (the set of possible values taken by the random variable) can be interpreted as providing a relative likelihood that the value of the random variable would be ... Webobservable ex ante variable. Therefore, when the Fisher equation is written in the form i t = r t+1 + π t+1, it expresses an ex ante variable as the sum of two ex post variables. More formally, if F t is a ﬁltration representing information at time t, i t is adapted to the ﬁltration F t while π t+1 and, in consequence, r t+1 are adapted to the ﬁltration F
