dependents_plot
Visualises dependents of one variable on another.
Plots conditional statistics. The statistics plotted by default is the conditional mean. However, any other statistics also can be plotted.
For example, let's assume that you have two metrics:
- duration of atrial fibrillation during 24 hour ambulatory ECG recording (stored in vector 'holter').
- peak ischemic ST depression during cardiac stress test (stored in vector 'ST').
and you need to analyse the conditional probability distribution of the former on the later.
Use the following commands to initialize the variables:
>> N = 1e5;
>> ST = 2*pi*(1:N)/N;
>> holter = sin(ST) + randn(size(ST));
Show E(holter|ST):
>> dependents_plot(ST,holter)
Show E(holter|ST), conditional standard deviation, and maximum:
>> dependents_plot(ST,holter,[],{@mean, @std, @max})
Basically, you can show any statistics you need; all you need is to provide an appropriate function handle. For example, you can show different percentiles:
>> index_ = @(v,ii) v(ii);
>> perc = @(v,p) index_(sort(v(:)), max(round(numel(v)*p/100),1)); % find percentile (p= 0..100)
>> dependents_plot(ST,holter,[],{@(z) perc(z,10), @(z) perc(z,30), @median, @mean, @(z) perc(z,70), @(z) perc(z,90)});
>> legend('10%','30%','median','mean','70%','90%')

1.1 | Bug fix : elements where X was equal to max(X) were counted in the lowest bin instead of the highest bin. Also, change behavior of map2bins when mode=='center' or vBins is a number: the first and the last bins are now extended to infinity. |
