Convert quarterly time series to monthly time series - donnertrud - May-21-2020 Hi, in order to bring all my data sets in the same shape, I need to convert a data set consisting of quartlery dates into a data set consisting of monthly dates. Here is a sample : Date Feature 2000/03 1.1 2000/06 0.9 2000/09 0.5 2000/12 0.6 What I would like to have is: Date Feature 2000/01 1.1 2000/02 1.1 2000/03 1.1 2000/04 0.9 2000/05 0.9 2000/06 0.9 Moreover, in order to get more accurate values for each month, I need the data to be interpolated. Any hint how I could do that? thanks in advance! Edit : Sorry i could not figure out proper formatting, and thus it looks a little bit ugly If anyone encounters the same problem, here is the solution : For resampling : dataframe = dataframe.resample('1M').mean() 1M can changed to D ( Days ) aswell, mean() fills the "empty" values with the mean For interpolation : dataframe['Column'] = dataframe[['Column')].interpolate(method="linear") other interpolation methods exist, like polynomial and so on RE: Convert quarterly time series to monthly time series - pyzyx3qwerty - May-22-2020 Please use proper code tags while posting a thread.
