|
x |
Vector of x-values |
y |
Vector of y-values |
degree |
Degree of the b-spline to fit to the data |
num.knots |
A scalar or vector of the number of knot points to be considered. e.g. 3:5 or just 3. |
sigma.jitter |
MCMC tuning parameter: the size of jumps for the knot point locations. |
sigma.split |
MCMC tuning parameter: how far apart knots end up when we split one. |
chain.length |
How long a MCMC to create. |
start.point |
A list of starting points |
burn.in |
The length of chain to be considered 'burn in'. |
num.chains |
How many chains to create. |
num.jacobians |
How many randomly selected jacobians to average for each step of the MCMC. |
