On estimating parameters of a multi-component Chirp Model with equal chirp rates
Abhinek Shukla, Debasis Kundu, Amit Mitra +1
Multi-component chirp signal models with equal chirp rates appear in various radar applications, e.g., synthetic aperture radar, echo signal of a rapid mobile target, etc. Many sub…
Estimation methods for elementary chirp model parameters
Anjali Mittal, Rhythm Grover, Debasis Kundu +1
In this paper, we propose some estimation techniques to estimate the elementary chirp model parameters, which are encountered in sonar, radar, acoustics, and other areas. We derive…
A Computationally Efficient algorithm to estimate the Parameters of a Two-Dimensional Chirp Model with the product term
Abhinek Shukla, Rhythm Grover, Debasis Kundu +1
Chirp signal models and their generalizations have been used to model many natural and man-made phenomena in signal processing and time series literature. In recent times, several…
Order Restricted Inference for Adaptive Progressively Censored Competing Risks Data
Ayon Ganguly, Debanjan Mitra, Debasis Kundu
Under adaptive progressive Type-II censoring schemes, order restricted inference based on competing risks data is discussed in this article. The latent failure lifetimes for the co…
Bayesian Inference of a Dependent Competing Risk Data
Debashis Samanta, Debasis Kundu
Analysis of competing risks data plays an important role in the lifetime data analysis. Recently Feizjavadian and Hashemi (Computational Statistics and Data Analysis, vol. 82, 19-3…
Analysis of Left Truncated and Right Censored Competing Risks Data
Debasis Kundu, Debanjan Mitra, Ayon Ganguly
In this article, the analysis of left truncated and right censored competing risks data is carried out, under the assumption of the latent failure times model. It is assumed that t…
An efficient methodology to estimate the parameters of a two-dimensional chirp signal model
Rhythm Grover, Debasis Kundu, Amit Mitra
In various capacities of statistical signal processing two-dimensional (2-D) chirp models have been considered significantly, particularly in image processing to model gray-scal…
Parameter Estimation of absolute continuous four parameter Geometric Marshall-Olkin bivariate Pareto Distribution
Biplab Paul, Arabin Kumar Dey, Arjun K Gupta +1
In this paper we formulate a four parameter absolute continuous Geometric Marshall-Olkin bivariate Pareto distribution and study its parameter estimation through EM algorithm and a…
Asymptotic of Approximate Least Squares Estimators of Parameters Two-Dimensional Chirp Signal
Rhythm Grover, Debasis Kundu, Amit Mitra
In this paper, we address the problem of parameter estimation of a 2-D chirp model under the assumption that the errors are stationary. We extend the 2-D periodogram method for the…
A new decision theoretic sampling plan for type-I and type-I hybrid censored samples from the exponential distribution
Deepak Prajapati, Sharmistha Mitra, Debasis Kundu
The study proposes a new decision theoretic sampling plan (DSP) for Type-I and Type-I hybrid censored samples when the lifetimes of individual items are exponentially distributed w…
On a General Class of Discrete Bivariate Distributions
Debasis Kundu
In this paper we develop a very general class of bivariate discrete distributions. The basic idea is very simple. The marginals are obtained by taking the random geometric sum of a…
Chirp-like model and its parameter estimation
Rhythm Grover, Debasis Kundu, Amit Mitra
We propose a chirp-like signal model as an alternative to a chirp model and a generalisation of the sinusoidal model, which is a fundamental model in the statistical signal process…
