Interest Rate Fundamentals

Day-count Convention / Year Fraction: We denote by )τt( , T the chosen time measure between t and T, which is usually referred as the year fraction between t and T. When t and T are less than one day, )τt( , T is to be interpreted as T – t (in years).

Using STATA for mixed-effects models (i - School of Public ...

For mixed models with no nested grouping structure, thinking of the entire estimation data as one group is . convenient. Toward this end, xtmixed allows the special group designation _all. xtmixed also allows the factor . variable notation R.varname, which is shorthand for describing the levels of varname as a series of indicator . variables.

the common factor of dx 1 dx 2 dx 3, we obtain1 ρ ∂2u i ∂t2 = ∂ jτ ij +f i. (3.8) This is the fundamental equation that underlies much of seismology. It is called the momentum equation or the equation of motion for a continuum. Each of the terms, u i, τ ij and f i is a function of position x and time. The body force term f generally ...

Chapter 9 The exponential family: Conjugate priors

(9.15) From these results we see that the relative values of α1 and α2 determine the mean, whereas the magnitude α1 + α2 determines the variance. That is, for a fixed value of the mean, the variance goes to zero as α1 +α2 goes to infinity. Applying these results to the posterior distribution in Eq. (9.10), we can compute the posterior ...
