The limitations due to exposure detection limits for regression models.

Original Contribution The Limitations due to Exposure Detection Limits for Regression Models

Biomarker use in exposure assessment is increasingly common, and consideration of related issues is of growing importance. Exposure quantification may be compromised when measurement is subject to a lower threshold. Statistical modeling of such data requires a decision regarding the handling of such readings. Various authors have considered this problem. In the context of linear regression anal...

Using Regression based Control Limits and Probability Mixture Models for Monitoring Customer Behavior

In order to achieve the maximum flexibility in adaptation to ever changing customer’s expectations in customer relationship management, appropriate measures of customer behavior should be continually monitored. To this end, control charts adjusted for buyer’s/visitor’s prior intention to repurchase or visit again are suitable means taking into account the heterogeneity across customers. In the ...

ارزیابی میدان‌های الکتریکی و مغناطیسی لامپ‌های کم مصرف از نوع فلورسنت فشرده از دیدگاه حفاظت پرتوی

The technology used in energy-saving compact fluorescent lamps (CFLs), provides a quarter of the energy consumption of incandescent lamps to produce equivalent light energy while CLFs shelf life is up to ten times of incandescent lamps. So the incandescent lamps in homes and workplaces are replaced with CFLs. Due to the use of ballast in the structure of CFLs, electric and magnetic fields are g...

Using Classic Discriminant Analysis and Detection Function for Separation of Chemical Victims in Sardasht City to Exposed and Non Exposure Mustard Groups in 2013 and Comparison with Logistic Regression

ارزیابی پرتوهای فرابنفش لامپ‌های کم‌مصرف از نوع فلورسنت فشرده

Iranians are replacing traditional incandescent lamps with Compact Fluorescent Lamps (CFLs), because they use about a quarter of the power of incandescent lamps and their lifecycle is up to ten times longer. Government encourages public to use CFLs too, for saving energy and reducing carbon dioxide emissions. Small amounts of mercury are used in CFLs, released to the environment if they are bro...
