Null-hacking, a lurking problem
PsyArXiv Preprints
John Protzko: “Pre-registration of analysis plans involves making data-analysis decisions before the data is run in order to prevent flexibly re-running it until a specific result appears (p-hacking). Just because a model and result is pre-registered, however, does not make it reflective of underlying reality. The complement to p-hacking, null-hacking, is the use of the same questionable research practices to re-analyze open data to return a null finding."Mistic, an open-source multiplexed image t-SNE
The Mathematical Oncology Blog
Sandhya Prabhakaran: “We were interested in understanding if and how treatment changed the tumor patterns across patients, and whether these patterns were predictive of patient response. As part of image pre-processing that involved cleaning and segmenting these images, we were also keen in arranging the images in a specific manner to visually bring out underlying patterns that would otherwise have been hard to detect. This was the motivation and need to develop Mistic, which is an open-source image t-SNE viewer for simultaneous viewing of multiple multiplexed 2D images using predefined coordinates (e.g. t-SNE or UMAP), randomly generated coordinates, or as vertical grids.”
The newsletter now has a dedicated homepage (thisweekmathonco.substack.com), which allows us to post cover artwork for each issue. We encourage submissions that coincide with the release of a recent paper from your group.
Caption: The Galton board of phenotypic plasticity and resistance to therapy. An untreated tumour falls through a Galton board organized by treatment sensitivity, where the left most trajectories represent treatment resistance (purple cells) and the rightmost trajectories represent regrowth of a sensitive (orange cells) tumour. Transitions between drug sensitive and tolerant states is random and illustrated as a tumour bouncing in either direction-- towards drug resistance or sensitivity. Applying treatment closes the gates and biases the tumour’s trajectory towards resistance or regrowth. The tumour’s path is determined by both its current state; its history, as an explicit representation of stochastic phenotypic inheritance; and when treatment is applied, with the aim of selectively closing gates to direct the tumour towards extinction. In our recent work, we developed a simple mathematical model of this non-genetic phenotypic memory and fit the model to ex vivo NSCLC data. Using a combination of classical techniques from population dynamics, we derived simple thresholds that determine which gates to close to direct the tumours evolution away from resistance and towards extinction.
