Nice Tutorial Sir, but I'm confused that according to VCI formula the maximum and minimum NDVI will be the previous year but here you used NDVI max min for the same year that you wanted to calculate for VCI, how Sir??
He is right, not past year "Where NDVI is the current NDVI value, NDVImin is the minimum NDVI value and NDVImax is the maximum NDVI value of the research period"
Thank you for your comment, @MehrnoushEghtedari In the provided code, the Standardized Precipitation Index (SPI) is calculated directly using a formula that computes the difference between the current precipitation and the long-term average precipitation, divided by the standard deviation of the long-term average precipitation. This direct calculation method is commonly used in practice to assess precipitation anomalies. While fitting a probability distribution function to the data is another approach to calculate the SPI, it requires additional steps such as fitting a distribution like the gamma distribution or Pearson Type III distribution to the precipitation data. This approach can provide valuable insights into the distribution of precipitation anomalies but is more complex and not implemented in the code shared here.

The Vegetation Condition Index (VCI) can be calculated using different approaches depending on the context and the purpose of the analysis. In the video, I used the maximum and minimum NDVI values from the same year to focus on intra-annual variability, which helps to highlight the vegetation condition within that specific year. However, it's also common to use the maximum and minimum NDVI values over a longer period, such as several years, to capture inter-annual variability and provide a more comprehensive view of vegetation conditions over time. This approach can help in identifying long-term trends and anomalies. Both methods are valid and useful in different scenarios. For a more detailed analysis, you can consider the specific goals of your study and choose the method that best suits your needs.
excellent video sir, thank you.
Thanks alot

Is the probability function not fitted to calculate the SPI?
