Compute Statistics

This module enables users to plot the relationship between any 2 variables (genes) or observations. The plot type is automatically chosen based on the selection. For each combination, appropriate statistical computations are performed. A Standard Compute runtime is required.

Command Form

The command form captures the information required to run the compute statistics analysis.

• Subset (optional) - A data slice

• Variable 1 (required) - A gene or observation present in the dataset

• Variable 2 (required) - A gene or observation present in the dataset

• Color / Grouping (optional) - An observation used to group the values

• Drop cells/samples with zero counts - Applies only to genes. Removes all entries with zero counts to prevent skewing the plot.

Combinations table

Combination	Plot Type	Additional Computations
Gene v. Gene	Scatter plot	Correlation, Regression (OLS)
Gene v. Cont. Observation	Scatter plot	Correlation, Regression (OLS)
Gene v. Categ. Observation	Box plot	ANOVA, Tukey's Test
Cont. Obs. vs Cont. Obs	Scatter plot	Correlation, Regression (OLS)
Cont. Obs vs Categ. Obs	Box plot	ANOVA, Tukey's Test
Categ. Obs vs Categ. Obs	Matrix plot	Chi-squared Test

Results

Results can be displayed in either a tile view or a grid view. Use the buttons next to the search bar to toggle the mode.

The quick search bar is visible only for tile view and it offers an easy way to get to any result. The name of the result is used for searching.

Tile View

Each result in the tile view is a static plot generated based on the types of variables inputted.

Tile view

Grid View

Each row in the grid represents a result. To view a result, click on a row.

Grid view

Result Details View

The compute statistics result page contains 2 or 3 tabs, depending on the types of variables chosen.
