Measuring ease of access to transit services is important in evaluating existing services, predicting travel demands, allocating transportation investments, and making decisions on land development. A composite index to assessing accessibility of public transit is described. It involves use of readily-available methods and represents a more holistic measure of transit accessibility, integrating...

It is known that composite quantile regression estimator could be much more efficient and sometimes arbitrarily more efficient than the least squares estimator. In this paper, tests for the index parameter and index function in the single-index composite quantile regression are considered. The asymptotic behaviors of the proposed tests are established and their limiting null distributions are d...

An index theory is presented for compact absorbing contractive Jc or SJc maps and several new fixed point theorems are given for such maps. AMS(MOS) subject classification: 47H10

Researchers have adopted online data such as search query volumes to forecast tourism demand for a destination, including tourist volumes and hotel occupancy. However, the massive yet highly correlated query data pose challenges when researchers attempt to include them in the forecasting model. We propose a framework and procedure for creating a composite search index adopted in a generalized d...

The modulation of tropical cyclone activity by the Madden–Julian oscillation (MJO) is explored using an empirical genesis potential (GP) index. Composite anomalies of the genesis index associated with the different MJO phases are consistent with the composite anomalies in TC genesis frequency that occur in the same phases, indicating that the index captures the changes in the environment that a...

In current Chinese Security Market, stock or main index running orbit is a complicated phenomenon. In this paper, proposed a method to forecast Shanghai composite index using time series volume, turnover rate, close price, high price, low price, and open price as parameters. In order to simulate Shanghai composite index’s running orbit we improve a new partial differential equations simulation ...

A new extension of the generalized topological indices (GTI) approach is carried out to represent “simple” and “composite” topological indices (TIs) in an unified way. This approach defines a GTI-space from which both simple and composite TIs represent particular subspaces. Accordingly, simple TIs such as Wiener, Balaban, Zagreb, Harary and Randić connectivity indices are expressed by means of ...

the interest for the spatial dimensions of agricultural development has been recently increased. this paper aimed at redefining the spatial patterns of agriculture to formulate appropriate strategies based on regional potentials. a composite agricultural development indicator (cadi), which is useful for the identification of spatial structure, has been developed. the developed composite index (...

The finite-range voter system, one of stochastic particle systems, is applied to model a financial price process for further description and investigation of fluctuations of Shanghai Composite Index. For different parameter values of the intensity and the range R , we investigate the statistical behaviors of the simulation data for this financial model. Then we develop the random jump time effe...
