Here, T = 3K 1, 3K two, 3K three, indicating the initial month, second month, and third month nowcast. At every single new release date (q, T), model parameters are updated with new data added in the new released series, and nowcast of yK 1 is re-produced. Tips on how to deal with this unbalanced information in our BAY approach will probably be discussed in details in Section 3. three. Estimation System and Nowcasting In Section 3.1, we introduce the Bayesian MCMC algorithm to estimate model parameters and latent elements and to decide the amount of contributing aspects. In Section 3.2, nowcasting formulas are offered. 3.1. Estimating Dynamic Aspect Models Employing Bayesian MCMC In this section, we first introduce our process of implementing the unbalanced information into our model framework naturally. Then, we finish our model specification by assigning priors in Bayesian Framework. Ultimately, the MCMC process is discussed in detail. As discussed in Section two, macroeconomic series are released with diverse lags in actual time. Hence, a difficulty in real-time nowcasting would be to take care of unbalanced information. Within this section, we create a computational Bayesian MCMC strategy which will tackle this problem naturally. To take care of the missing data in xivq,t at the end with the sample, we introduce the nq n indicator matrix 1vq,t by deleting the ith row from the identity matrix 1n if i vq,t . / For the example discussed in Section two, at the third releasing date (3, T) in month T, v3,T -1 = 1, 2, 3, 4. Hence, removing the fifth and sixth row of 16 offers us 1 0 = 0 0 0 1 0 0 0 0 1 1 0 0 0 0 0 0 0 0 0 0 . 01v3,T-Mathematics 2021, 9,7 ofSimilarly, for the index set v3,T = 1, 2, deleting the final four rows of 16 results in 1v3,T = 1 0 0 1 0 0 0 0 0 0 0 .Then, we are able to just rewrite xivq,t as xivq,t = 1vq,t xt . To improved derive the posterior distributions, we express the dynamic of xt in Equation (1) as: xt = [ I n n Ft ] t , exactly where = vec = (1 , . . . , n) , i is often a 1 R vector representing the ith row of , i = 1, 2, . . . , n, and the symbol denotes the Kronecker solution. As a result, for the qth releasing date in month T, the conditional density for xt is xt |Ft , , N ( [ I n Ft ] ,) 1vq,t xt |Ft , , N (1vq,t ( [ I n Ft ]), 1vq,t 1vq,t) the conditional density of Ft is Ft |Ft-1 , A, N (AFt-1 ,), f or t = 2, . . . , T, and the conditional density of yk is yk |F3k , F3k-1 , F3k-2 , yk-1 , S, two N ( 0 1 SF3k two SF3k-1 3 SF3k-2 four yk-1 , 2), (9) for k = two, . . . , K. Within this way, the unbalanced structure of the data is constructed into our model framework by means of this indicator matrix 1vq,t . Let = ( , , A, , , , S, two) denote all parameters to become estimated. Suppose we are at releasing date q in month T of quarter K 1, our activity is to use observations Y = y1 , . . . , yK and Xq,T = x1 , . . . , xTq , xivq,Tq 1 , . . . , xivq,T to estimate parameters and latent variables F1 , . . . , FT , then condu.
