getTransitionProbability {HVT}

Creating Transition Probabilities list

Description

This is the main function to create transition probabilities list. The transition probability table quantifies the likelihood of transitioning from one state to another. States: The table includes the current states and the possible next states. Probabilities: For each current state, it lists the probability of transitioning to each of the next possible states.

Usage

getTransitionProbability(df, cellid_column, time_column)

Arguments

df

Data frame. The input data frame should contain two columns, cell ID from scoreHVT function and time stamp of that dataset.

cellid_column

Character. Name of the column containing cell IDs.

time_column

Character. Name of the column containing time stamps.

Value

Prints and stores a nested list of data frames with transition probabilities.
