nanmean - Mean ignoring NaNs

Syntax

m = nanmean(X)
m = nanmean(X,DIM)

Arguments

Description

nanmean for financial times series objects is based on the Statistics Toolbox function nanmean. See nanmean in the Statistics Toolbox documentation.

m = nanmean(X) returns the sample mean of a financial time series object X, treating NaNs as missing values. m is a row vector containing the mean value of the non-NaN elements in each series.

m = nanmean(X,DIM) takes the mean along dimension DIM of X.

Examples

To compute nanmean for the following dates:

dates = {'01-Jan-2007';'02-Jan-2007';'03-Jan-2007'};
f = fints(dates, magic(3));
f.series1(1) = nan;
f.series2(3) = nan;
f.series3(2) = nan;

nmean = nanmean(f)

nmean =

    3.5000    3.0000    4.0000
