I have returns marked in a column of 1*20million column. It has a specific value as -10, but I am not able to find out where it is.
I have tried using
but couldnt interpret the ouput. -
0×1 empty double column vector
When I check this matrix, its blank and does not even give any answer. Can someone guide on this?
I also wanted to plot these returns and histogram for this-
But I just get the x and the y axis. The reason could be i have 20 million rows and thus, its not visible in the graph. Can we show these values, in this graph, rather than just showing the x and y axis as it gives a vague picture.
nbins = 4000; %i have calculated the appropriate bins
However, I am just getting everything at a point. I want to see the distribution and its should mostly be normally distributed or highly skewed towards right.
