Calculating SPI index using R studio | Video Tutorial

Hello Guys,
In this video I will guide you through the R studio interface on how to determine the SPI index from precipitation data.
The link to video on How to install R studio:
Hope you found this useful :D

Thank you so much
great video
We wish to make videos about:
1 How do you calculate the Palmer Drought Index?
2 How do you calculate climate extremes?
Thank you so much

Thanks a lot this was very helpful. How do you then interpret the spi values ? do you like find the average spi value which you can use to draw conclusions?

it's really great and can u please explain how can i calculate SPI for multiple stations, actually i'm having many stations for one district, how can i consider all stations ? means is it necessary to do for every station ?

[mohamedfomba]

Thank you very much for your interesting video.
Please, I would like to know how did you set up the spei formulas in the different sheets to get the plots directly after adding data from R?

Hello. Why i can not see months in the result?

[badygo]

Please! How to solve #REF! when editing?Why 1978 -A in the table?

Thank you very much for your video on SPI. But, I have a question, that how to add missing values.

[mahsumbozdogan]

Hi. I get this warning when I type the formula spi3<-spi(projectSPI$prcp, 3):

[1] "Calculating the Standardized Precipitation Evapotranspiration Index (SPEI) at a time scale of 3. Using kernel type 'rectangular', with 0 shift. Fitting the data to a Gamma distribution. Using the ub-pwm parameter fitting method. Checking for missing values (`NA`): all the data must be complete. Using the whole time series as reference period. Input type is vector. No time information provided, assuming a monthly time series."

Can you help me?
Thanks.

How to change the study period in your file, would appreciate your quick response

I have 109 stations, for which I have daily precipitation values. Please tell me how to prepare data from this for SPI ??

bro how can we get plots in excel after adding data from R

I'm getting spi values but below that I'm not getting year values

how can I get years like 1975, 1980, in plots

[mashiwanigasuriya]

thanks a lot.🥰🥰🥰...wow wow😍 very interesting and useful video🥰

[soumago]

please how can I modify the horizontal axis value, to use dates instead of numbers?

[ritujhalani]

Is that necessary to use all monthly rainfall data in excel sheet or I can take 5 months data (may- September)

[ResNeeD]

I support you for your good information

@Red Fish I got a REF error from 2018 to 2020? what to do for that.

[alvinofadilah]

Hallo, can you help me process SPI data? I want to ask for an example of this processing in this excel

[feyeneregassa]

Thank you it's so supportive video.

[Hydro-SolutionTube]

Sir, which version of R studio you are using?

[amelieu]

Hello, I got SPI values but there are no months included along the values. How can i fix it?
