Apparent Non-Response to Phosphodiesterase Type 5 Inhibitors in Erectile Dysfunction: A Narrative Review of Structured Reassessment and Management [PDF]
MedicinaBackground and Objectives: Apparent non-response to phosphodiesterase type 5 (PDE5) inhibitors is common, but the label conflates inadequate instruction or drug exposure, partial or absent response, treatment discontinuation, and coexisting clinical ...

Restructured searls family of estimators of population mean in the presence of nonresponse
Frontiers in Applied Mathematics and Statistics, 2022 Nonresponse is a major problem encountered by surveyors when conducting sampling surveys. The present study suggested a naïve modified Searls method for the elevated estimation of the population mean of the primary variable under investigation by ...

An Efficient Estimation Procedure for the Population Mean under Non-Response
Statistica, 2020 This paper introduces an efficient estimation procedure for the population mean in the presence of non-response. The proposed estimators of population mean provides an improvement over the corresponding conventional estimators proposed by Cochran (1977),

A New Fuzzy Multiobjective Geometric Programming in Double Sampling in Presence of Non-Response
IEEE Access, 2020 Non-linear programming problems can be solved efficiently by geometric programming in which non-linear expressions can be expressed by an exponential or power functions. In this paper, Double Sampling Stratification (DSS) strategy is used in multivariate

Understanding the patterns of mode switching in longitudinal studies
Survey Research Methods, 2021 Using mixed-mode data collection is becoming a mainstream way of conducting longitudinal surveys. However, interviewing the same units in a mixed-mode longitudinal design can lead to respondents switching between modes over time.

Communications in Advanced Mathematical Sciences, 2023 Throughout this article, a two-phase sampling (TPS) technique is employed to estimate the population mean of the sensitive variable. The current article endeavours to develop a chain ratio type estimator for the estimation of sensitive variable(s) in the
