Description:
A Simulation-Based Guide Using SAS
In A Practical Approach to Quantitative Validation of Patient-Reported Outcomes, two distinguished researchers, with 50 years of collective research experience and hundreds of publications on patient-centered research, deliver a detailed and comprehensive exposition on the critical steps required for quantitative validation of patient-reported outcomes (PROs). The book provides an incisive and instructional explanation and discussion on major aspects of psychometric validation methodology on PROs, especially relevant for medical applications sponsored by the pharmaceutical industry, where SAS is the primary software, and evaluated in regulatory and other healthcare environments.
Central topics include test-retest reliability, exploratory and confirmatory factor analyses, construct and criterion validity, responsiveness and sensitivity, interpretation of PRO scores and findings, and meaningful within-patient change and clinical important difference. The authors provide step-by-step guidance while walking readers through how to structure data prior to a PRO analysis and demonstrate how to implement analyses with simulated examples grounded in real-life scenarios.
Readers will also find:
A thorough introduction to patient-reported outcomes, including their definition, development, and psychometric validation
Comprehensive explorations of the validation workflow, including discussions of clinical trials as a data source for validation and the validation workflow for single and multi-item scales
In-depth discussions of key concepts related

Keeps skin moisturized like a lotion
This is quite a lot larger than I thought it would be when I picked it. It's sized like a lotion bottle. My skin can get dry sometimes, especially in the winter so I picked this up to help prevent it from cracking. This is working well so far.
It's unscented which is what I prefer. I'm not fond of scented oils or lotions on my face and hands. This works very well as a lotion. It melts and absorbs into the skin without leaving any extra color or residue. There's a little bit of a oil sheen to it, but it doesn't stand out. It does not have the oil or grease feeling to it which is great.
It's worked really well this winter. My hands and face are moisturized and looking great. I got this in December 2025 and it expires October 2028. I'll probably use it up before it expires.

Amazingly good
This by far, is the very best product and formulation that I've ever used on my face. I have super sensitive skin and have tried three different brands before trying this. The others I've tried, either had a beefy smell after a little while or contained essential oils that irritated my skin. I almost gave up. This was my last try and I'm so glad I gave it a chance. Absolutely no smell and no irritating essential oils or ingredients. It is very soothing and absorbs completely. Thank you Veakoo!! I will definitely keep using this and will be purchasing more. This is a wonderful product and has helped sooo much!

Great product!
Style: Deep Moisturizing, Size: 1.76 Fl Oz (Pack of 1)
I love this stuff! My mom introduced this to me while I was visiting her, and within 3 days of using it I knew I needed to order one for myself. It has no smell, goes on buttery soft, and soaks in well. It is not heavy at all. At night I layer it on thicker and during the day I put a very thin layer on under my makeup. My skin is so much softer and hydrated. I have had small bumps on my cheeks for so long and they were gone within 3 days. My skin looks dewy and soft.
I read reviews of other brands that smelled, were oily, or too heavy. This is none of those things and it is a great price!
