Stata. I have a longitudinal data set in a long format, with columns for age, day of year, weight and height. I have successfully used the following model but would like to go a few steps further: nl (weight ={A=500}*(1-{b=0.9}*exp(-{k=0.003}*age))^{M=0.5}), ...
repeated measures modelTrial‐based cost〆ffectiveness analyses (CEAs) are an important source of evidence in the assessment of health interventions. In these studies, cost and effectiveness outcomes are commonly measured at multiple time points, but some observations may be missing. Restricting the...
In this model, the interactive effects are also considered as random: (αB)jk ∼ NID(0, σ2αB) and their E(MS) are built on the principle of considering as random any term that contains at least one random component without any restriction, which is also known as the non-restricted...
A zero-restriction model would be one in which individuals can be vaccinated by any service provider. This refers to the factors influencing the entry or use of health care services, in this case, covid-19 vaccination [32]. The information on restrictions was identified by analyzing the level...
