Plots of range of values for coefficient in model with log-likelihoods
for the model with the coefficient fixed at these values.
For each coefficient a range of possible values is chosen, given by
\(\hat{B}*mult_{lower} - \hat{B}*mult_{upper}\).
A series of models are fit (given by interval
).
The coefficient is included in the model as a
fixed term and the partial log-likelihood for the model is calculated.
A curve is plotted which gives the partial log-likelihood for each of these candidate values.
An appropriate confidence interval (CI) is given
by subtracting 1/2 the value of the appropriate quantile
of a chi-squared distribution with \(1\) degree of freedom.
Two circles are also plotted giving the 95
