How to Calculate Standardized Precipitation Index (SPI) using Precintcon Package in RStudio

In this video, I have clearly shown the steps required to Calculate SPI using Precintcon Package in RStudio

[@carinabe7473]

Hi Fitsum, which R version are you using? It's because prec-package is not available for R version 3.5.1. Thx!

[@laura.taro_]

God bless you! Thank you

Hi Fitsum, Thank you for these very useful videos. Can you make a video on calculating Temperature anomalies and making graphs in R studio. Thank you

[@karelsanchez3476]

Hi, Fitsum, Thank you. I would like to ask if its possible to download it, because the link doesn't allow it. Thank you

[@GOTJISIRICH]

Please tell me.
I use Precinton Package.
How to calculate SPI3, SPI6, SPI9 and SPI12? Thank you

what does thisspi-3,6,9 values mean?

[@helcibsaavedracuero2066]

hello, i have a question. i do not have daily data but an average of precipitation data for each month from 1981 to 2019 and following the steps gives me error and does not give the results of spi. I would like to know how I could get the SPI from monthly and non-daily average data.

Hi Fitsum, We can monthly also by > spi(as.monthly(diredawa,na.value = NA), period) Kno? Reply

[@Emeritus63s]

Good day I would like to get to know how you would present your data in the result section

[@chandrakantkadam1953]

Very Good information. What if the multiple stations are there in the study area? How to prepare data for that

Hi Fitsum, Great thanks for these useful videos but how can export this results to excel pls i have facing with for omitted results in spi pls help

[@tekkisilikdevkadro_iro]

Hi, I tried the application but got the following error " Error in spei(data, scale, kernel, distribution, fit, na.rm, ref.start, : argument "scale" is missing, with no default" What can I do? Can you help me?

[@kefelegnchernet1289]

Thank you, but please tell me if the data is monthly. Didn"t work.

[@smaranikamahapatra335]

Can this package be used for calculating standardised streamflow index?

[@NEXTLevelGISRSfitsalem]

No, use DrinC

[@brunnatomaino2519]

Hello, Thanks for you explanation. For me does not appear na.value, only na.contiguos, na.pass.. etc)

[@shanikhan783]

How can i calculate for monthly missing values in data set

[@amounaimen5107]

I have error in rowsums(object[3:33], na.rm=TRUE) :must be numeric
What does it mean plz ?

[@shreenijmaharajan5152]

same did you find any solution

Hi, How to calculate monthly decade (year = 1-36 and month = 1-3, 1:10,11:20:21:30/28/31) using R

[@nandalalpeiris1732]

PREC package cant install. It says package ‘PREC’ is not available (for R version 3.6.0). how can i solve this problem.

[@shivanigond3403]

how can we calculate spi using monthly precipitation data??

[@marcelolatuf601]

Access drought.unl.edu/droughtmonitoring/SPI/SPIProgram.aspx (University of Nebraska)

[@andreash6978]

It is easy. Instead of "as.daily" simply use "as.monthly" after the spi-function. Note that the data needs to be arranged according to year, month and monthly precipitation (i.e. data only in 3 columns).

[@mridulmahajan8768]

"Error in precintcon.spi.analysis(object, period, distribution) :
input data should be of type precintcon.daily or precintcon.monthly"
This error again and again

[@mokuaretang7155]

i think daily
