how to omitt columns with only nan values when calculating means across mutiple tables?

Hi all,

I have a 21x1 cell with 100x 18 tables

I am calcuating mean of:

row 1, column1, all tables

row 2, column1, all tables

....

row 100, column 1, all tables

I repeat for remaining 17 columns, so ultimately, I have a table 100x18.

    table=zeros(100,18);
for k=1:18
    table_mean=table+table2array(my cell{k});
end
table_mean= table_mean/18

Howewever, some of the columns in a few tables have only 'nan' values. Is there a way to omitt those columns in my calculations?

Answer 1

This omits all NaNs from the mean calculation.

load('mycell.mat');
n_tables = numel(t_sq_dot_1);

% put all tables' data into a 3D array: 100x18x21
all_data = zeros([size(t_sq_dot_1{1}),n_tables]);
for ii = 1:n_tables
    all_data(:,:,ii) = table2array(t_sq_dot_1{ii});
end
% alternate approach, using cellfun() and {:,:} indexing instead of 
% a for loop and table2array():
% all_data = cellfun(@(x)x{:,:},t_sq_dot_1,'UniformOutput',false);
% all_data = cat(3,all_data{:});

% take the mean along the 3rd dimension, omitting NaNs
table_mean = mean(all_data,3,'omitnan');
disp(table_mean)

And if you want your result back in a table (so you have your variable labels in the end):

table_mean = array2table(table_mean,VariableNames = t_sq_dot_1{1}.Properties.VariableNames);

Also, data in a table variable can be n-dimensional, so you could have started with a 100x18 table, each of whose variables is 100x21 (or even 100x1x21). Then, you could use varfun to calculate the mean of each variable. In this case, I think @_'s solution is more efficient.

Thanks @_ @Eric Sofen

Eric

When I run it I get:

Error: Incorrect use of '=' operator. 
To assign a value to a variable, use '='. To compare values for equality, use '=='.

Any idea how could I also calculate standard deviation? I tried by

table_std = std(all_data,3,'omitnan');

which gives me

Error in std (line 59)
y = sqrt(var(varargin{:}));

[Voss]

When I do that, I get a different error:

load('mycell.mat');
n_tables = numel(t_sq_dot_1);
nr = size(t_sq_dot_1{1},1);

% put all tables' data into a 3D array: 100x18x21
all_data = cellfun(@(x)x{:,:},t_sq_dot_1,'UniformOutput',false);
all_data = cat(3,all_data{:});

% set all elements in any column of all_data to NaN when any element in
% that column is NaN:
all_data(repmat(any(isnan(all_data),1),nr,1,1)) = NaN;

% take the std along the 3rd dimension, omitting NaNs
try
    table_std = std(all_data,3,'omitnan');
catch ME
    disp(ME.message);
    table_std = std(all_data,0,3,'omitnan'); % the correct way to use std here
end % error message below:

W must be a vector of nonnegative weights, or a scalar 0 or 1.

disp(table_std)
