python - Evaluating a Gaussian Fit -


i'd know ways determine how gaussian function fitting data.

here few plots i've been testing methods against. currently, i'm using rmse of fit versus sample (red fit, blue sample).

for instance, here 2 fits:

good fit

enter image description here

and here 2 terrible fits should flagged bad data:

enter image description here enter image description here

in general, i'm looking suggestions of additional metrics measure goodness of fit. additionally, can see in second 'good' fit, there can other peaks outside data. currently, these penalized rsme method, though should not be.

i'm looking suggestions of additional metrics measure goodness of fit.

the one-sample kolmogorov-smirnov (ks) test starting point.

i'd suggest wikipedia article introduction.

the test available in scipy scipy.stats.kstest. function computes , returns both ks test statistic , p-value.

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.

javascript - IE11 incompatibility with jQuery's 'readonly'? -

the code i'm running has no issues in firefox, or chrome. user typing 1 textbox, tabs next , can continue typing that. when run webpage on ie11, user tabs next textbox , can't type in. textbox has double-clicked before user can insert anything. i've googled , seems ie give problems when using older jquery (i.e. prefers 'prop' 'attr' ). in code below jquery's readonly keyword being used in way ie11 no longer recognise/accept? i assume issue readonly , removeclass('ignore') working expected. //when focus on textbox 1 $("#field1").focus(function() { //remove readonly property textbox 1 $('#field1').prop('readonly', false).removeclass('ignore'); //add readonly property other textboxes $('#field2, #field3, #field4') .prop('readonly', 'readonly').addclass('ignore').val(''); }); i'm using jquery 2.1.3 ...
