Dynamic hierarchical factor model
Weba dynamic hierarchical factor model that is able to decompose inflows in a sample of 47 economies into (i) a global factor common to all types of flows and all recipient countries, (ii) a factor specific to a given type of capital inflows, (iii) a regional factor and (iv) a country-specific com-ponent. Webexible hierarchical (multi-level) dynamic factor model. The hierarchy is produced by splitting a large panel of data into a much smaller number of blocks, each of which consists of a reasonably large number of series. We assume that each block is driven by factors that are common amongst series within the block,

WebRes = dfm (X,X_pred,m,p,frq,isdiff,blocks, threshold, ar_errors, varnames) Main function for estimating dynamic factor models. The first six arguments are required; the remaining four are optional. S = KF (Y, A, HJ, Q, R) Fast Kalman filtering adding each series sequentially (and thus avoiding matrix inversions). WebDynamic Hierarchical Mimicking. Official implementation of our DHM training mechanism as described in Dynamic Hierarchical Mimicking Towards Consistent Optimization Objectives (CVPR'20) by Duo Li and Qifeng Chen on CIFAR-100 and ILSVRC2012 benchmarks with the PyTorch framework..

WebAbstract. This article surveys work on a class of models, dynamic factor models (DFMs), that has received considerable attention in the past decade because of their ability to model simultaneously and consistently data sets in which the number of series exceeds the number of time series observations. The aim of this survey is to describe the ... WebThe model used here is an approximate dynamic factor model for large cross-sections. This model provides a parsimonious representation of the dynamic co-variation among a set of random ariables.v Consider an n-dimensional vector of commodity returns x t = (x 1t;:::;x nt)0. Under the assumption that x t has a factor representation, each series x
WebApr 9, 2024 · In this paper, we propose a novel local attention module, Slide Attention, which leverages common convolution operations to achieve high efficiency, flexibility and generalizability. Specifically, we first re-interpret the column-based Im2Col function from a new row-based perspective and use Depthwise Convolution as an efficient substitution. WebDynamic Hierarchical Factor Models ... new dynamic factor model that exploits the block structure of data releases by statistical agencies, information on the sectoral structure of the economy, and prior views about how economy activity might be related across market, region, industry etc. to improve the estimation and interpretation ...
