[Numpy-discussion] t-statistic

[Sudheer Joseph]

Dear experts,
                 I am doing a project involving regression of a model variable with observed variable and wanted to find t-values dynamically as the number of available observations involved in comparison changes. Is there a tool in numpy/scipy which gives the appropriate t-value if we give number of samples ?

t = 2.31				# appropriate t value (where n=9, two tailed 95%)

with best regards,
Sudheer
