Lung cancer case study: Two examples of the rescaled marked point data from NLST dataset, where black, red and green points represent lymphocyte (○), stromal (+) and tumor (Δ) cells. For the data shown in the left, $\widehat{\lambda }=172.102$, ${\widehat{\pi }}_{\text{lym}}=0.022$, ${\widehat{\pi }}_{\text{str}}=0.173$, ${\widehat{\pi }}_{\text{tum}}=0.805$ and ${\widehat{\varphi }}_{\text{tum},\text{ str}}=0.012$ For the data shown in the right, $\widehat{\lambda }=169.268$, ${\widehat{\pi }}_{\text{lym}}=0.011$, ${\widehat{\pi }}_{\text{str}}=0.603$, ${\widehat{\pi }}_{\text{tum}}=0.386$ and ${\widehat{\varphi }}_{\text{tum},\text{str}}=0.162$.
