Does anyone know how i can deal with this in the most efficient manner? Note: There would be about 20+ lines looking like the one below... cast((base.[XXX_DataSetB] - base.[XXX_DataSetA]) as decimal) / base.[XXX_DataSetB] as [XXX_Percentage]

• Converting Numpy Lstsq residual value to R^2

  - by whatnick

  I am performing a least squares regression as below (univariate). I would like to express the significance of the result in terms of R^2. Numpy returns a value of unscaled residual, what would be a sensible way of normalizing this. field_clean,back_clean = rid_zeros(backscatter,field_data) num_vals = len(field_clean) x = field_clean[:,row:row+1] y = 10*log10(back_clean) A = hstack([x, ones((num_vals,1))]) soln = lstsq(A, y ) m, c = soln [0] residues = soln [1] print residues

• How to check if a string has earlier been set using iabbr (full match)

  - by Sumit

  I am trying to check if a lhs is already abbreviated in vim. mapcheck, however, seems to have a problem. For example, iabbr swt switch echo mapcheck('sw','i',1) returns "switch" even when "switch" defined for "swt". mapargs seem to return a string even if there is a partial match with the lhs. Is there a way to find if an abbreviation has been defined for the "exact" match, i.e., the above mapcheck returning a "" instead.
