Spatially consistent imputations of forest data under a semivariogram model

a study on insurer solvency by panel data model: the case of iranian insurance market

the aim of this thesis is an approach for assessing insurer’s solvency for iranian insurance companies. we use of economic data with both time series and cross-sectional variation, thus by using the panel data model will survey the insurer solvency.

A Consistent Estimator for Uniform Parameter Under Interval Censoring

‎The censored data are widely used in statistical tests and parameters estimation‎. ‎In some cases e.g‎. ‎medical accidents which data are not recorded at the time of occurrence‎, ‎some methods such as interval censoring are used‎. ‎In this paper‎, ‎for a random sample uniformly distributed on the interval (0,θ) ‎the interval censoring have been used‎. ‎A consistent estimator of θ  and some asy...

[Multiple imputations for missing data: a simulation with epidemiological data].

In situations with missing data, statistical analyses are usually limited to subjects with complete data. However, such estimates may be biased. The method of 'filling in' missing data is called imputation. This article aimed to present a multiple imputation method. From a data set of 470 surgical patients, logistic models were developed for death as the outcome. Two incomplete data sets were g...

investigating the feasibility of a proposed model for geometric design of deployable arch structures

deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
