In ctmm-initiative/ctmmweb: Web App For ctmm

• Variograms of individuals in current subset are plotted here.
• Empirical variograms are added with a layer of automatic Guesstimate parameters.
• You can further fine-tune the parameters by selecting individual in the drop down list.
  • The drop down list support search filter and direct editing.
  • There will be a pop up window for fine-tune parameters.
  • Center current values will update sliders range to twice of current value, so it's easier to deal with very small or large values.
  • Apply butto will accept adjusted parameters and update the variogram.
• Alternative information criteria can be selected before moving to next step of model fitting, which can be useful for certain case like small samples.
• Moving to Modeled tab will try various models with current guesstimate parameters as initial condition.
