RobPer: AnRPackage to Calculate Periodograms for Light Curves Based on Robust Regression

Some Modifications to Calculate Regression Coefficients in Multiple Linear Regression

In a multiple linear regression model, there are instances where one has to update the regression parameters. In such models as new data become available, by adding one row to the design matrix, the least-squares estimates for the parameters must be updated to reflect the impact of the new data. We will modify two existing methods of calculating regression coefficients in multiple linear regres...

در سالهای اخیر،اختلالات کیفیت توان مهمترین موضوع می باشد که محققان زیادی را برای پیدا کردن راه حلی برای حل آن علاقه مند ساخته است.امروزه کیفیت توان در سیستم قدرت برای مراکز صنعتی،تجاری وکاربردهای بیمارستانی مسئله مهمی می باشد.مشکل ولتاژمثل شرایط افت ولتاژواضافه جریان ناشی از اتصال کوتاه مدار یا وقوع خطا در سیستم بیشتر مورد توجه می باشد. برای مطالعه افت ولتاژ واضافه جریان،محققان زیادی کار کرده ...

Robust testing for superiority between two regression curves

where mj : R → R is a nonparametric smooth function and the error εj is independent of the covariate Xj. As is usual in a robust framework, we will assume that the errors εj are such that εj = σj Uj, where Uj has a symmetric distribution Gj(·) with scale 1, so that we are able to identify the error’s scale, σj. When second moments exist, as it is the case of the classical approach, these condit...

Adaptive Contouring – an efficient way to calculate microlensing light curves of extended sources

The availability of a robust and efficient routine for calculating light curves of a finite source magnified due to bending its light by the gravitational field of an intervening binary lens is essential for determining the characteristics of planets in such microlensing events, as well as for modelling stellar lens binaries and resolving the brightness profile of the source star. However, the ...
