well the variables load on the different factors. A factor is reliable if it has: 3 or more variables with loadings of 0.8 and any n 4 or more variables with loadings of 0.6 and any n 10 or more variables with loadings of 0.4 and n≥150 Factors with only a few loadings require n≥300

Posterior Predictive Distribution - University of South ...

Posterior Predictive Distribution I Recall that for a fixed value of θ, our data X follow the distribution p(X|θ). I However, the true value of θ is uncertain, so we should average over the possible values of θ to get a better idea of the distribution of X. I Before taking the sample, the uncertainty in θ is represented by the prior distribution p(θ).

Convolution, Correlation, Fourier Transforms

Autocorrelation • The correlation of a function with itself is called its autocorrelation. – In this case the correlation theorem becomes the transform pair – This is the Wiener-Khinchin Theorem Corr(g,g)↔G(f)G*(f)= G(f)2

Tim Bollerslev (1986) extended the ARCH model to allow ˙2 t to have an additional autoregres-sive structure within itself.

Correlation in Random Variables

Autocorrelation Function The autocorrelation function is very similar to the covariance func-tion. It is defined as R(X,Y)=E[XY]=cov(X,Y)+E[X]E[Y] It retains the mean values in the calculation of the value. The random variables are orthogonal if R(X,Y)=0. Lecture 11 5
