ORTHOGONAL POLYNOMIALS FOR CURVE FITTING INTRODUCTION One of the statistical problems which has received a great deal of attention from mathematicians for a good many years is the problem of fitting a theoretical curve to a set of observed data. The usual procedure is to use the method of least squares to determine a theoretical equation in powers of x. But when the theoretical curve desired is of higher than second or third degree, the work of determining the coefficients becomes very great. For a polynomial of degree k, k+l equations must be solved simultaneously for the k~l coefficients. Theoretically, of course, these can be solved, but in practice k does not have to be very large to discourage any but the most pa­ tient and industrious persons from attempting to solve them. To simplify the work of determining a theoretical equation, various types of orthogonal functions have been introduced. The function may be represented by a series of sines or cosines, by a series of Legendre's polynomials, or by a series of polynomials made up of factorials. Tchebycheff first worked in this last field, and more recently some improved forms of the ortho gonal polynomials have been suggested--among which are Fisher's ~-polynomials, theY-polynomials used by Sasuly, and Jordan's polynomials. This thesis deals with polynomials which differ from those of Jordan only by a simple multiplier. 2 The most important case is the one in which the observed independent variates form an arithmetic pro­ gression . points . Suppose observations have been made at n+l By a simple transformation these n+-1 points may be transformed into the points 0 , 1 , 2 , 3 , ••... , n , and it is in this form that the data must be , if it is to be fitted to a regression curve consistinb of a series of these finite orthogonal polynomials . lf the points are not eaually spaced , the work of this thesis does not apply, (unless the data may be grouped in some manner so that the resulting points are equally spaced . ) To work with these polynomials , some knowledge of the calculus of finite differences is needed . Here, the fac ­ torial function x(n).x (x-l)(x-2) • • ••• (x-n+l) takes the place of the power function xn in the infinltesimal case . The following formulas will be needed .

LEGENDRE'S EQUATION AND ITS ANALOG IN FINITE CALCULUS The dii'i'erential equation ~ [(l-x2)~}m(m+l)y:O is known as Legendre's equation. Since it is a second order equation, it will in gen­ eral have two linearly independent solutions. But at the points x:-1 and x=l the equation degenerates into a first order equation, so there will be only one solution possible at these points. If the substitution x:2s-l is made, these critical points are transformed into the points s=O and s=l, and Legendre ' s equation becomes (2) In the calculus of finite differences the equation analogous to (2) is the difference equation ·f1tS[S-{"Yl+1)] fl/A(S-J)}- Wl(YVl+l) [;{(s} ==0. l3) This difference equation may be expressed in a some­ what different form. By actually taking the differences in (3), (and combining terms in the result), we obtain the equation (5+ 1)(11-s)U(stJ)+[2s(s-n)-)1+WI(YVI+tTI i{(s)+S{YJ+ l-s)~(s-1)=0. .

PROPERTIES OF THE POLYNOMI ALS The polynomials Pm,n(s) have the orthogonal property. Consider two of these polynomials Pm,n(s) and Ph,n(s) . Each satisfies the difference equation (3), so we may start with the equations and Multiply the first of these equations by Ph,n(s), the second by Pm,n(s), and subtract. the limits s=O and ~ Then if the sum between is taken, the result is L Ph,Y>(slLl{s [s-1-n+Jl]L'I Pm,Y>(s-1)] S=O )1 - L_ f:n,Y> (s) Ll{S [S-(1mll Ll fh,.nls-1)] 5=0 -[YY!(Yn+l) -hi h+ 1)] t 5=0 Pm,Y>(s) fh,,,lsl= 0. 12 The first two of these sums may b e evaluated by summation by parts .

Indeed , t h e polynomials Pm, n(s) may themselves be derived directly from this property--not making use of the differe nce e quation at all . 13 Assume polynomials (C) which satisfy the equations 11 ~,11 (s) Pm,,(s):::: 0 [_ .S:.O 1 (k = 0, I, 2,3,.

(e) This is permissable , since (s+k)(k) may be expanded (n+k) ( k ) in a series of polynomials Pm n ( s) , the degree of none of which is greater than k .

Substitute this value for Q(k) in e quation (g) and multiply through by the common denomin a tor to obt a in the e qu a tion In this equation set k = -1, which will give the result m! =(-I ) -m m{c . Therefore , C= (-l) m. Then in e auation (h) set k = - q-1 (where q is a positive integer not gr eater than m) , and obtain the result Therefore , 16 Then the polynomials we assumed are This formula is exactly the same as (6) which was obt&ined as a solution of the dif1erence equation (3). It will now be necessary to evaluate ~ Pm2, n{ s) .

It is also useful as a check for the values of Pm, n(s) as calculated in Table 1. The sum of the squares of the numbers in any given column must be equal to the value as calculated by (9). , Another formula which is of use when tables of Pm n(s) are calculated is the formula for Pm , n(l) . Substituting s =l in formula (6), all terms vanish except when q• O and q=l , and after simplification the formula becomes ~)r1 (i) ,vhen calculating a column of fie;ures in the table of Pm, n( s), one will find immediately by means of this formula if mistakes have been made in reducing the general e quation for Pm n(s) to ' a simplified form for the special value of m and n represented by that column in the table . 19 In order to calculate Pm, n ( s ) for values of m and n higher than those given in table 1 , use may be made of the following recursion formulas : (Yn+ 1Xn- YYJ) ~+r)n(s) + (z. rn+ 1)(zs- Y1) Pm> Yl {s) + Y¥1 (Yl-t- m + 1) ~-~} 11 (s) ==D) (I 0) 20 3. CURVE FITTING In this chapter the problem of fitting a regression or trend curve to a set of n+l equally- spaced points by the method of least squares will be considered . Suppose the independent variable is t and that the n+l independent variates are t 0 , t1 , t 2 , ••••• , tn . If the transformation si=ti _to n is made , the points t i will be transformed into tn- to the points s 0 =o , s 1 =1 , s 2 . 2 , •.••••••• , sn• n . In this form the data may be utilized in the work that follows . If it is decided to use ·a curve of degree k , the fitted value will be given by (12.) where the A ' s are constants to be determined in such a q manner that 21 is a minimum . To insure this , differentiate partially with respect to the Aq ' s , and obtain k+l equations of the form Because of the orthogonal property , all of the terms drop out except the one containing Am . So each of the k+l equations reduces to an equation of the form Making use of equation ( 9 ), it follow s that { ) A.. -Zm+IY1 - ln + fn +J (f1rl) )'»!+') I 'I t_ Pl'n s s /1.1 Is). \] l1 { ) > (13) =0 This sum is not difficult to evaluate , although if n were very large , it would of course involve c onsiderable arithmetic computation . Another of the advantages of these polynomials is brought out in equation (13 ). Supp ose one has cal­ culated the coefficients for & curve of degree k . If it 22 is then decided that a curve of higher degree would be better, only the coefficients Ai where i ) k would need to be calculated, since the first k~l coefficients would be the srume as they were in the k-th degree equation, because (as equation (13) shows), the value of Am is entirely independent of k. Very often it would be useful to know how much vari­ ation there is between the observed data and the fitted curve. The mean square deviation of the observed from the theoretical values is the measure usually considered. square root of this quantity is called the "mean and is denoted by o-~ The er~or 11 2 • Algebraically CJh is given by the equat~· == n~l cr~(s)- ~At~,)1(sf This may be written in the Uk 2 for~ =~~ ~'\s)-2 ~ + Since a-; 2.

Table B. The data is given in Since the volume of a log of given length is proportional to the square of the diameter, it would seem that a parabolic curve should fit the data, unless other factors (such as methods of cutting, etc.) have an unusual effect not evident on the surface of the problem. *Rider, Paul, Statistical Methods, John Wiley and Sons, New York, 1939, pp. 124-125. 32 Table B·l} Volume of 16-foot Logs According to Scribner Log ·Rule Diameter in inches 6 8 10 12 14 16 18 20 22 24 26 28 30 32 34 36 38 40 Point Number Observed Volume Theoretical Volume s y ( s) y '(x) 0 18 32 54 79 114 159 213 280 334 404 500 582 657 736 800 923 1068 1204 12.0 30.3 54.8 85.7 122.9 166.4 216.2 272.3 334.7 403.4 478.5 559.8 647.4 741.4 841.6 948.2 1061.1 1180.2 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 The theoretical curve will be plotted without ever finding its equation.

In order to obtain the actual value of Pm , n(s) as given by equation ( 6) , it is necessary to divide the table value by the table value of Pm n(O) . ' Table 2 contains values of Kk , n(s , x) (see equation (15 )).
