Goal: To see if there is a correlation between the protrusion parameters matrix and the math of the cells using linear regression. Training matrices: DMSO treated cells (in order): cell 14, cell 15, cell 12, cell 10 CK666 treated cells (in order): cell 43 ,cell 48 , cell 55 , cell 53 variables: Count, largest protusion volume, total protustion volume, protrusion fraction, largest protrusion length, largest protrusion angle, and total protrusion angle. Experiment 1Dependent value (y): derivative using savitzkygolay variables:
To get rid of rows without Y values training.set.complete<training.set[complete.cases(training.set),] I did this because the smoothing window on the sg filter leaves a lot of blank values for the derivative. Results: all the parameters were significant except largest protrusion angle, and total angles. The largest protrusion length is only significant for the first few fits. Experiment 2Dependent value (y): curve method variables:
Experiment 3Dependent value (y): bimodal with cutoff (ie, is the cell turning or not turning?)
Results:
To do next:
add more cells to the training set write function to find average turning point prediction
