Type of the returned array, as well as of the accumulator in which the elements are multiplied. 8 Nan is returned for slices that are all-NaN or empty. Below are additional functions (© Kara Lavender), that compute covariance matrix and EOFs from incomplete data. 将金融时间序列对象 (. nansum converts its input to a numpy array, so it effectively loses the column information (sum doesn't do this). Steven Lord on 4 Nov 2016. For matrices, nanmean(X) is a row vector containing the mean of the non-NaN elements in each column. The data set has some missing values as well. so I thought you use nanmean and nansum to ignore nans with grpstats, but it seems that it always ignores them. For more information, see Compatibility. nansum# numpy. 0 Nan is returned for slices that are all-NaN or empty.
