Hi everyone,

I am currently working with the following article:
The elephant in the stats | The Economist

My question are:
Is the GDP Deflator a reliable indice for the growth rate of India? Yes,no and why?

I don't really understand the message of the text (My English is not good enough). So is the majority of the economist trusting the GDP Deflator more than the WPI, CPI or the general growth rate.
How is the GDP Deflator rated in the text? Can someone help me?
