conclusions addressing and removing explainable patterns of syndromic data on meningitis is necessary to timely and accurately detection of meningitis epidemics. it was concluded that decomposition methods had better performance compared to the model based ones. background meningitis is one of the most disturbing infectious diseases due to mortality, morbidity and its ability to cause epidemic....

We characterize Pareto efficient long term ‘relational’ lending contracts with one-sided lender commitment in a context where the borrower can accumulate wealth, has intertemporal consumption smoothing preferences, and some sanctioning power following default. show negative results of Bulow Rogoff (1989) do not apply irrespective extent sanctions, borrower's preferences for smoothing, initial w...

This paper analyses two schemes of single-stage diode-switched active filters used in new switching power supplies designs to improve the power factor. From the point of view of the power flow, the distortion reduction is based on the improvement of the power conversion processes. Most of the ca/cc switching power supplies consists of two separated parts: a rectifier – in most cases a diode bri...

In this paper, we consider three major types of nonparametric regression tests that are based on kernel and local polynomial smoothing techniques. Their asymptotic power comparisons are established systematically under the fixed and contiguous alternatives, and are also illustrated through non-asymptotic investigations and finite-sample simulation studies. MSC : primary 62G10; secondary 62G05, ...

This article demonstrates the visual power of continuous smoothing and slicing of multivariate maps, through an example relating the rates of screening tests to colon cancer rates. A new theoretical result provides legitimacy and understanding by demonstrating how the conditional maps are related to the usual single smoothed choropleth map of colon cancer rates.

The main objective of this study was to investigate the effect of income smoothing on investors reaction to Earnings Persistence of companies listed on the Stock Exchange in Tehran. The population of the study was companies listed on the Stock Exchange in Tehran, the sample size due to screening method and after removing outliers is equal to 118 companies. In this study, earnings persistence an...

Simple exponential smoothing (SES) methods are the most commonly used methods in forecasting and time series analysis. However, they are generally insensitive to non-stationary structural events such as level shifts, ramp shifts, and spikes or impulses. Similar to that of outliers in stationary time series, these non-stationary events will lead to increased level of errors in the forecasting pr...
