Actually I need to estimate a zero-inflated model bacause the gamma regression itself do not adequately fit the data. 0 Likes Reply SteveDenham Jade | Level 19 Re: Zero-Inflated Gamma Model - NLMIXED - SAS 9.4 Posted 07-01-2016 01:23 PM (6805 views) | In reply to Luca...

Multivariate logistic regression analysis was performed to investigate the relationship between various factors and APIP using Statistical Applied Software (SAS student version).Compared with normal pregnant women, APIP patients have elevated values in alanine aminotransferase (ALT), aspartate aminotransferase...
Cox proportional hazards regression analysis was used to identify the association between γ-GT level and dementia after adjustment for other risk factors. The results were presented as HRs and 95% CI. Subgroup analysis was performed according to covariates including sex, age, hypertension, previous ...

(Gy). Linear regression between cuttings survival and gamma ray doses was estimated. According to the LD50radiation dose, 36 Gy was determined as the appropriate gamma dose rate during the experiment26. In next year, 2000 dormant buds on 1-year-old pomegranate shoots were subjected to gamma ...
The relation among age (25–34; 35–44; 45–55 years), BMI (16–22.9; 23–26.9; 27–32 kg/m2) and incident diabetes were examined within three categories of GGT (0–19; 20–39; ≥40 U/l) by linear and logistic regression analyses. The SAS statistical program, version 8.0, was ...
Considering the appreciable correlation between GGT and CA19–9, we fitted a multivariate Cox regression model that included both CA19–9 and GGT in the subset of the 97 PDAC patients with baseline CA19–9 measurements: elevated GGT was still a significant prognostic factor (HR = 1.53, ...
Unconditional logistic regression analysis was used to estimate OR and corresponding 95% confidence intervals (CI) for disease development using co-dominant, dominant and recessive models for each SNP, respectively, adjusting for age and sex. In additional sensitivity analyses, the associations of the ...
